By Rufus Mather Bagg, Jr., Of the University of Illinois , Urhana, Illinois. While the examination of this material was in progress, after about 100 species of Foraminifera had been identified and described, almost the entire collection was destroyed by fire and the original scale of the report thus had to be abandoned. It is possible to give only a summary of the results derived from a study of the material saved from the fire, which consists of 19 bottles containing chiefly typical Globigerina and Pulvinulina ooze. The species, over 200 in number, represent 54 genera and are mostly characteristic of warm waters in tropical oceans. The following method was used in the examination of the ma- terial: On a fine-grained cloth of double thickness in a long porce- lain tray were poured the contents of each vial. Additional alcohol was used to thoroughly wash this ooze, and the Foraminifera were spread out on the cloth, which was then lifted out and dried over a lamp. The shells were easily shaken from the dried cloth, not dried together in lumps, and a soft brush removed from the cloth the very finest portion of the ooze that might be left after shaking. The forms thus selected were clean and white and could be spread out on black cardboard for microscopic examination. The remainder of the alcoholic solution, with the finest mud and ooze, was allowed to settle in the tray, and, with the label, was returned to the bottle from which it had been taken. With this method any radiolaria or diatoms that may have been present were left in the solution and can be further studied. The mechanical sediment likewise was saved, and the frag- ments of any other organisms that might be present. It was found best to examine most of the material in reflected light, and the tests were most readily studied upon a black background, for which pur- pose I used thick glossy cardboard which had been glued to a glass slide.

The mounting and extraction of Foraminifera can be accomplished in many ways. An excellent description of such work is to be found in Chapman’s The Foraminifera (chap, xix, pp. 291-326). It is, however, rather expensive and tedious to mount on separate cover under glass every species recognized, and I therefore used the follow- ing method : The specimen to be preserved was fastened with strong glue upon a slip of heavy white paper which had been blackened with india ink where the specimen was to be mounted. On this slip of paper was put also the number and description of the dredging sta- tion and the name of the species mounted. Two specimens upon dif- ferent surfaces are generally all that is required for future use, although it is desirable to have a side aspect of the test, and this re- quires some skill to keep the form in place until it is permanently fixed. If in future these forms are wanted for other purposes they can readily be detached by strong vinegar and washed quickly in alcohol and water. A wet brush enables one to pick up the tiny shells with considerable rapidity and to hold them in any desired position while studying them. Only brief descriptions of species have been given in most instances in this report, but new forms and also some of the more important known types have been discussed quite fully. The new forms are bottled separately and marked “ Type,” and have been deposited in the U. S. National Museum. While I have not separately mounted from every bottle of dredgings each species as it repeatedly occurred, every form identified has been selected and mounted by the method described, and in many instances a single form has been prepared again and again as particularly instructive and characteristic. In the arrangement of the classification of species given in this paper we have followed the order adopted by the British authorities on the Rhizopoda, W. K. Parker, T. R. Jones, W. B. Carpenter, and amended by H. B. Brady and the later writers, C. D. Sherborn and Frederick Chapman. The first reference of each form listed is that of the original descrip- tion of the species. Much valuable information has been obtained from the exhaustive monographs by Prof. H. B. Brady in the Chal- lenger Report, and by Dr. Alexander Goes on Arctic and Scandi- navian recent marine Foraminifera®, and the excellent report on recent Foraminifera by Dr. James M. Flint 6 . Mention should be made also of such invaluable works as Williamson’s Recent Foramini- fera of Great Britain (Ray Society, 1858) ; Brady, Parker, and Jones on some Foraminifera from Abrohlos Bank (1888) Chapman’s The a Kongl.

FORA MINIFERA FROM THE HA WAIIAN ISLANDS— BAGG. 115 Foraminifera (1902) ; and d’Orbigny’s Foraminifera of the Vienna Basin (1846), which have been found indispensable. There are some anomalies concerning the bathymetric range of a number of species mentioned in this report. The occurrence of few deep-water types in those stations beyond 1,000 fathoms is not easily accounted for, but it must be remembered that many of these Fora- minifera are of almost universal distribution, and some that are rec- ognized and described are not at all common or abundant and would not be considered as determining the probable depth of the ocean from whence they came. Systematists on the Foraminifera can not be too careful on this point. It is well known that the temperature of the great oceans is fairly constant below a few hundred fathoms, and the distribution of life is on the whole quite largely dependent upon the distribution of the food supply as well as upon temperature of the water in which these organisms live. Then again some forms are pelagic in habit and can easily be found after death in bottom material in an occasional specimen. It is but proper to state that we have considerable evidence of rather shallow water, say not over 500 fathoms, in the material studied, while the facts show that a number of the stations are considerably over 1,000 fathoms in depth. Those species which reach their maximum development and are most abundant in each station determine more safely the relative depth than do any occasional specimens obtained from the same locality. Bryozoa, Mollusca, both lamellibranchs and gastropods, are found in a number of bottles, also fragments of shells from stations below 200 fathoms, and this is rather hard to explain unless they have been carried outward by tidal or other ocean currents in rapid motion. The greatest variety of forms was obtained at Station 4694, from which 62 species were determined. The smallest number (4) came from Station 4579, where the material was chiefly mechanical sedi- ment. Mollusca were present in some of the . dredgings, particularly tiny gastropods, with an occasional lamellibranch, often very beauti- fully colored. Ostracoda of several genera were quite prominent. Diatoms and radiolarians in a few instances were met with, also fragments of corals and bryozoans. In a few bottles small mouth plates of fishes were present. There were a large number of sponge spicules (siliceous), and in some bottles fragments of volcanic glass and land-derived sand grains with opalescent quartz. Phosphatic nodules which dissolve very readily in acids appear in some localities. Most of the Foraminifera in this collection belong to calcareous types with perforate tests, but the Miliolidse are well represented in some stations. The species Candeina nitida , Globigerina cequilater- alis , Globigerina bulloides , Orbulina universa , Pulvinulina menardii , and Pulvinulina micheliniana are present in nearly every station’s 116 PROCEEDINGS OF THE NATIONAL MUSEUM.

FORAMINIFERA FROM THE HA W A IIA N ISLANDS— BA G G. 117 Subfamily MILIOLININ^]. Genus BILOCULINA. BILOCULINA BULLOIDES d’Orbigny. Biloculina bulloides d’Orbigny, Ann. Sci. Nat., VII, No. 1, 1820, p. 297, pi. xvi, figs. 1-4. Thick-shelled globose test with highly inflated segments and cir- cular aperture. The species belong to moderate depths and has been obtained in all the great oceans rather sparingly, but is more common in the North Atlantic. Occurs as stated above, and is best developed at depths ranging from 300 to about 1,000 fathoms. In the neighborhood of the New Guinea Islands this foraminifer has been obtained in very shoal waters. It is present at Albatross Stations D. 4000, D. 4025, H. 4555, and H. 4696. BILOCULINA COMATA Brady. Biloculina comata Brady, Quart. Journ. Microsc. Sci., XXI, n. s., 1881, p. 45. Similar to Biloculina bulloides , but with the surface covered by longitudinal striations, and the shell of large dimensions. Found with other biloculine forms in the North Atlantic and the Pacific oceans. Pare in the dredgings we have studied. Present only at Station D. 4000. BILOCULINA DEPRESSA d’Orbigny. Biloculina depressa d’Orbigny, Ann. Sci. Nat., VII, No. 7, 1826, p. 298, modele No. 91. Margin thin and angular, shell depressed as the name implies. The form is closely related to Biloculina ringens , but the latter has less sharply defined margin and a different aperture. If the foraminifers described and figured by Terquem and Berthe- lin from the Lias of Essey-les-Nancy under the name Biloculina lias- sica are identical with the present form the species occurs much earlier geologically than any of its congenitors. Its recent distribu- tion is similar to that of Biloculina bulloides given above. It was found at Stations D. 4000, D. 4174, H. 4430, H. 4502, H. 4566, H. 4567, H. 4568, H. 4585, and H. 4590. BILOCULINA DEPRESSA var. MURRHYNA Schwager. Biloculina murrliyna Schwager, Novara-Exped., Geol. Theil, II, 1866, p. 203, pi. vi, figs. 15 a-c. A variety of Biloculina depressa characterized by two angular spinous projections near the base of the test and placed symmetri- .cally apart from the median line. 118 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. This variety would appear to be rare, judging from the Challenger investigations, as Professor Brady mentions but four localities, two each from the North and South Atlantic and Pacific oceans. Dr. C. Schwager’s specimens came from the Pliocene of Nicobar Islands. This form was found at Station H. 4502, and was abundant at Sta- tion H. 4555. BILOCULINA IRREGULARIS d’Orbigny. Biloculina irregularis d’Orbigny, Foram. Amer. Merid., 1839, p. 67, pi. viii, figs. 22-24. This species does not reveal the characteristic biloculine habit of growth in its adult stage, but the test is globose and there are two major segments in the final development which are similar to Bilo- culina bulloides in their shape and position. The asymmetry ap- pears from the third segment, cutting one side obliquely like Poly- morphina types and appearing as a faint line on the outer surface of the shell neither depressed nor elevated. Biloculina ventricosa Reuss, is the same as this species, which can be distinguished from Biloculina sphaera by its milioline aperture and the extension of the ultimate chamber. The Challenger dredged this foraminifer from the neighborhood of the Canaries in 1,125 fathoms; off Sombrero Island, 450 fathoms; south of Pernambuco, 350 fathoms, and in mid-ocean in the South Atlantic from 1,415 fathoms. It was also obtained near the Fiji, Tahiti, and Papua islands at depths of 610, 620, and 1,070 fathoms, respectively. The Albatross found it only at Station 4696, where it was rare. The Septaria clays of Hermsdorf near Berlin and the salt beds of Wieliczka have furnished the species among other fossil Forami- nifera. BILOCULINA ELONGATA d’Orbigny. Biloculina elongate d’Orbigny, Ann. Sci. Nat., VII, No. 4, 1826, p. 298. Test resembling Biloculina ringens in outline and aperture but longer and much narrower, as the name implies. The species appears to be the equivalent of Bioculina bougainvillei and B. patagonica of d’Orbigny. The shell shows considerable variation, chiefly in amount of elongation and globosity. Unlimited in distribution and depth, but most abundant in the South Pacific. Specimens were obtained at Stations D. 4017, D. 4025, and H. 4567. no. 1603. FORA MINIFERA FROM THE HAWAIIAN ISLANDS— B AGO. 119 Genus SPIROLOCULINA. SPIROLOCULINA ACUTIMARGO Brady. Spiroloculina acutimargo Brady, Chal. Rept., IX, 1884, p. 154, pi. x, fig. 12-15. The carinate peripheral margin of this thin complanate foraminifer is its chief characteristic. It has been obtained at Bermuda, 435 fathoms, four stations in the South Atlantic, 350 to 1,425 fathoms, and three localities in the South Pacific, 15 to 255 fathoms, and also in shore sands of Madagascar. Present rarely at Stations D. 4174, D. 4025, and H. 4694. SPIROLOCULINA GRATA Terquem. Spiroloculina grata Terquem, Mem. Soc. geol. France, ser. 3, I, 1878, p. 55, pi. x, figs. 14, 15. A thin complanate Spiroloculina with striate surface and common in coral reef material down to 400 or 500 fathoms. First described in the Tertiary of the island of Rhodes. Occurs at Stations D. 4017, H. 4567, and H. 4694. SPIROLOCULINA LIMBATA d’Orbigny. Spiroloculina limbata d’Orbigny, Ann. Sci. Nat., VII, No. 12, 1826, p. 299. Common in shallow water and found down to 400 fathoms in tropical and subtropical oceans. Known also from the Septaria Clay of Germany and in the later formations of Italy and Sicily. Found at Station D. 4017 only ; depth, 305 fathoms. SPIROLOCULINA NITIDA d’Orbigny. Spiroloculina nitida d’Orbigny, Ann. Sci. Nat., VII, No. 4, 1826, p. 298. Common in coral tropical sands and in the inland Japan and Mediterranean seas. Found at Station D. 4017 only; depth, 305 fathoms. SPIROLOCULINA PLANULATA (Lamarck). Miliolites planulata Lamarck, Ann. du Museum, V, No. 4, 1805, p. 352; Anim. Sans Vert., VII, No. 4, 1822, p. 613. With the exception of two soundings mentioned by Parker and Jones, this species is limited to shoal waters in temperate and sub- tropical oceans. It is rather common also in coral shoal water sands in the Pacific and Indian oceans and Red Sea. Found at Stations D. 4025, H. 4508, and H. 4694. 120 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. SPIROLOCULINA TENUIS (Czjzek). Quinqueloculina tenuis Czjzek, Haidinger’s Nat. Abhandl., II, 1847, p. 149, pi. xiii, figs. 31-34. Inhabiting all great oceans. Abundant in the -South Pacific but less common in the North Pacific, and known from depths of a few fathoms down to 2,750. Professor Brady writes that the finest speci- mens come from moderate depths. Fossil in the Austrian Tertiary. Occurs at Stations D. 4000, D. 4017, H. 4440, H. 4571, H. 4590, and H. 4696. Genus MILIOLINA. MILIOLINA BICORNIS var. ELEGANS Williamson. Miliolina Mcornis var. elegans Williamson, Recent Foram. Gt. Britain, 1858, p. 88, pi. vii, fig. 195. Differs from the type M. bicornis in the regular symmetry of its chambers and in the uniform size and regular parallelism of the sur- face grooves. This striate form is rarely found at depths greater than 50 fath- oms. The method of growth as shown by Schlumberger is in. accord with that of d’Orbigny’s genus Adelosina , in which the megasphere j.s completely enveloped by the first chamber, which becomes lenticular. It then passes through the biloculine, milioline, triloculine, quadriloc- uline, and quinqueloculine stages. Our form very closely represents this quinqueloculine form and the aperture is in the end on a con- siderably lengthened tube. Unfortunately we have but one broken specimen of this interesting species. Miliolina bicornis is fossil in the London clay and the Paris Basin Eocene. MILIOLINA CUVIERIANA (d’Orbigny). Quinqueloculina cuvieriana d’Orbigny, Foram. Cuba, 1839, p. 164, pi. xi, figs. 19-21. Test consisting of five segments with sharp or subcarinate margins and smooth unornamented surface. It is the same as Q. lamarckiana figured on the same plate (figs. 14, 15). A shallow tropical water species particularly known around the region of Japan, the Phil- ippines, and the islands of the Eastern Archipelago. While it is one of the most common Miliolinse in the Albatross material, the number of specimens in each locality is small. Found at Stations D. 4000, D. 4017, D. 4025, H. 4555, II. 4590, and H. 4694. NO. 1603. FORAMINIFERA FROM THE HA WAIIAN ISLANDS— BA GG. 121 MILIOLINA LINNiEANA (d’Orbigny). Triloculina linnceana d’Orbigny, Foram.

It differs from Miliolina pulchella in its comparatively thin and outspread contour, which sometimes approaches that of S 'piroloculina, the costae being few, thick, and well marked. A nearly identical form is described in the Vienna Basin memoir with the name Quinqueloculina josephina.” h Limited to shallow tropical waters. Occurs at Stations D. 4174 and H. 4568. MILIOLINA OBLONGA (Montagu). Vermiculum oblonga Montagu, Test. Britain, 1803, p. 522, pi. xiv, fig. 9. A cosmopolitan species known from all areas and depths, but best developed in shallow temperate seas. Found at Station D. 4000 only. MILIOLINA PARKERI Brady. Miliolina parkeri Brady, Quart. Journ. Microsc. Sci., XXI, n. s., 1881, p. 46. Surface of the segments crenulated and sharply angled at their margins. With the exception of forms from the Red Sea this species is a coral reef form in the tropical region of the Pacific Ocean. Occurs at Stations D. 4000, FL 4566, and H. 4694. MILIOLINA SEPARANS Brady. Miliolina separans Brady, Quart. Journ. Microsc. Sci., XXI, n. s., 1881, p. 45. An anomalous wild-growing form like Quinqueloculina linnceana partly unrolled.

Resembling the typical form but more complanate and with broader, shorter segments, frequently emarginate at their umbilical borders and possessing transverse ridges of growth which are lacking in the typical species. Common along the English coast in shell sand. Occurs in every latitude and is known from all depths. Geo- logically its history dates from the early Eocene. Not very common, but present at Stations D. 4017 and H. 4694. MILIOLINA TRICARINATA (d’Orbigny). Triloculina tricarinata b’Orbigny, Ann. Sci. Nat., VII, 1826, p. 290, No. 7, modele, No. 94. Tricarinate miliolince are not at all rare, but this species is more widely distributed than its related form M. trigonula. The carinate feature is in M. tricarinata limited to the peripheral portion, the intervening portion being more or less gibbous, but the species is sub- ject to great variation and is perhaps easily confused with Miliolina trigonula. While having an almost unlimited geographical distribu- tion the species is also of great bathymetric range and is known from a few fathoms down to 2,350 fathoms. As a fossil, it is recorded from the early Tertiary. Found at Stations D. 4000, D. 4025, D. 4174, and H. 4694. MILIOLINA TRIGONULA (Lamarck). Miliolites trigonula Lamarck, Ann. du Museum, V, No. 3, 1804, p. 351 ; Anim. sans Vert., VII, No. 2, 1822, p. 612. Test regular triloculine, with smooth subspherical or elongate chambers and nearly circular end view. Distinguished from M. tricarinata by a difference in the roundness or angularity of the chambers. Of wide distribution in shoal waters, and more frequent in the temperate than in tropical regions. Absent in cold northern waters; found chiefly in temperate in-shore sands. Beyond 100 fathoms the form is said to be replaced by Miliolina tricarinata. Geological history, Tertiary to recent. Found at Stations D. 4000, D. 4017, D. 4025, H. 4568, and H. 4696. no. 1603.

Occurs at Station H. 4694 at a depth of 865 fathoms, which is its deepest recorded occurrence. Subfamily PENEROPLIDIN^S. Genus CORNUSPIRA. CORNUSPIRA FOLIACEA (Philippi). Orbis foliaceus Philippi, Enum. Moll. Sicil., II, 1844, p. 147, pi. xxiv, fig. 26. Test planospiral, with thin, flat, rapidly widening whorls, and while the surface has no decoration there are frequently curved transverse lines of growth as in many of the Gasteropoda. An allied form with carinate margin is Cornuspira carinata (Costa). Rare in Scandinavian waters and Greenland (Goes), not uncom- mon in the Pacific, and ranging from shallow depths down to about 1,500 fathoms. Professor Brady states that the best specimens come from depths between 300 and 600 fathoms. Present in the Eocene and later Tertiary. Recognized at Station D. 4017 only, but is not common. CORNUSPIRA INVOLVENS Reuss. Cornuspira involvens Reuss, Sitzungb. Akad. Wiss. Wien, XLVIII, 1863 (1864), Pt. 1, p. 39, pi. i, fig. 2. Recognized by its rounded tubular whorls, which closely embrace each other and yet allow each whorl to be seen on either surface. Geological history from Tertiary to recent. Has probably been confused with Jurassic and Cretaceous Ammodisci, which it resem- bles. Dr. A. Goes records the form in the Arctic and Norwegian waters at depths ranging from 30 to 180 meters. A shallow water cosmopolitan species. Observed at Stations D. 4017 and D. 4174. Genus PENEROPLIS. PENEROPLIS PERTUSUS (Forskal). 'Nautilus pertusus Forskal, Descr. Anim., 1775, No. 65, p. 125. The genus Peneroplis , like Orbiculina , represents great variety of form and degree of compression and elongation of chambers without altering the segment arrangement or method of growth. For this reason and because of the transitional forms, it becomes necessary to separate the genus into several distinct types around which must 124 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. cluster the larger varieties of the type. The test of the genus Pene- roplis is a planospiral, crozier-shaped, imperforate calcareous (por- cellaneous) shell, and bilaterally symmetrical. An elaborate treatment of the genus is given by Dr. W. B. Carpenter in the Introduction to the Study of the Foraminifera (pp. 84-92, pi. vii) . The surface of the shell is beautifully marked by transverse striae closely set and covering the entire surface, as a rule, but there are also occasional pits in the shell substance which resemble pores, though the shell is nevertheless imperforate. The genus can be well subdivided into the following types : A. Peneroplis pertusus (Forskal). Nautiloid moderately com- pressed, involute shell with dendritic aperture. B. Peneroplis planatus (Fichtel and Moll). Broad complanate forms, striated surface and with a single row of pores on the septal face. C. Peneroplis arietinus (Batsch). Chambers at first involute, later nodosarian and numerous. Aperture a series of pores on the compressed anterior margin. D. Peneroplis cylindraceus (Lamarck). Test less compressed than in P. arietinus and more nearly nodosarian. *E. Peneroplis lituus (Gmelin). Chambers few, cylindrical, no- dosarian, but slightly irregular and of uneven size. F. Peneroplis carinatus d’Orbigny. Near variety P. pertusus but more involute and with sharp periphery and less decorated surface. G. Peneroplis loevigatus. Karrer. This is the most compressed type, somewhat resembling Operculina adunca , and the latter whorls embrace nearly two-thirds of the shell. I find two types of the above genus, P. pertusus and P. planatus , the former occurring at Station 4017, the latter at Station 4694. PENEROPLIS PERTUSUS var. PLANATUS (Fichtel and Moll). Rautilus planatus Fichtel and Moll, Test. Microsc., 1803, p. 91, pi. xvi, figs. 1 d, c, /. Found only at Station H. 4694 and is rare. The genus is usually found at less than 30 fathoms.

Nonionina canariensis d’Orbigny, Foram. Canaries, 1839, p. 128, pi. ii, figs. 33, 34, Known from all oceans and at all depths. Found as a fossil but not earlier than the Pleistocene. Specimens obtained at Stations H. 4566 and H. 4696 are rather more symmetrical and possess more chambers than some of the figured types of the species. The arena- ceous test, rounded periphery, depressed umbilici, and complanate character of the chambers are sufficient to distinguish this from allied forms. HAPLOPHRAGMIUM GLOBIGERINIFORME (Parker and Jones). Lituola nautiloidea globigeriniformis Parker and Jones, Phil. Trans., CLV, 1865, p. 407, pi. xv, figs 46, 47. This species is described with some doubt. There are only a few specimens, from Station 4585, which appear to belong here. They do not possess so many Globigerina-like segments and these are not so distinct, but the growth appears trochoid and the forms are con- ditionally placed here. Essentially a deep-water foraminifer of universal distribution. HAPLOPHRAGMIUM LATIDORSATUM (Bornemann). Nonionina latidorsata Bornemann, Zeitschr. deutsch. geol.

Haplophragmium nanum Brady, Quart. Journ. Microsc. Sci., XXI, n. s., 1881, p. 50. Somewhat similar to II. canariense , but with the segments more distinct and lobulated, and in its inequilateral development only upon the upper surface are all the segments visible. Recorded in the Chal- lenger report as characteristic of cold northern and southern latitudes and at depths of from about 50 to near 2,000 fathoms. Found only at Station H. 4694. HAPLOPHRAGMIUM SCITULUM Brady. Haplophragmium scitulum Brady, Quart. Journ. Microsc. Sci., XXI, n. s., 1881, p. 50. Test closely involute, nautiloid with depressed umbilici, arenaceous dark-brown test and rough exterior. Segments numerous, narrow, straight, but slightly depressed septa. Forms somewhat resembling Cyclammina cancellata occur at Station 4508 and the septal lines are not quite so regular as in the type-specimens. This species is closely related to II. latidorsatum , which is, however, less symmetrical, and has a thicker, coarser test and a more lobulated margin. Eleven localities for this species are reported in the Challenger records, eight of which were in the North Atlantic, 530 to 1,445 fathoms, one in the South Atlantic, one in the South Pacific, and one from very deep water in the North Pacific. Present at Stations H. 4430, H. 4508, H. 4585, and H. 4696. Doctor Flint mentions it from the west coast of Cuba and the west coast of Patagonia, 93 to 541 fathoms. Genus CRITHIONINA. CRITHIONINA PISUM var. HISPIDA Flint. Crithionina pisum var. hispida Flint, Recent Foraminifera, 1899, p. 267, pi. vi, fig. 2. The genus Crithionina was established recently by A. Goes and made to include minute Foraminifera, which are largely constructed of sponge spicules and exceedingly fine gray arenaeeous matter, and with a labyrinthic or cavernous, more or less spherical, chamber. This is undivided and the aperture is indistinct and divided. The hispid variety is even smaller than Crithionina pisum and is easily distinguished by its spinous sponge-spicule surface. There is appar- ently no visible aperture. 128 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. Kecorded by Dr. J. M.

Lituola soldanii Jones and Parker, Quart. Journ. Geol. Soc., XVI, No. 184, 1860, p. 307. Test stoutly built, nodosarian-like and of arenaceous coarse ma- terial. The internal subdivisions of the chambers do not appear on the surface. Without sectioning the aperture is the only means of distinguishing this species from Clavulina cylindrical as stated under the description of that species. This is the only living representative of the genus and is best de- veloped in the warm waters of the West Indies at shoal depths. It is also found in the Gulf of Mexico, 196 and 210 fathoms (Flint), and around many islands of the Pacific. It is variously recorded in the European Tertiary.

Subfamily LOFTUSIIX^]. Genus CYC LAMM IN A. CY CLAM MINA CANCELLATA Brady. Cyclammina cancellata Brady, in Norman, Proc. Roy. Soc., XXV, 1876, I). 214. The genus Cyclammina , established by Brady in 1876, includes the entirely arenaceous, large, compressed, convoluted Foraminifera whose walls are finely cancellated. These are often so highly devel- oped that the inner portion of the chambers is greatly reduced. Ex- ternally the surface is smooth and the aperture either a series of pores on the septal face or an arched fissure at the inner margin of the final segment. The periphery jn C. cancellata is rounded. I have identi- fied this species in the New Jersey Miocene but am not aware of its further occurrence in the fossil state. In existing oceans it is of very great bathymetric range (75 to 2,900 fathoms) and has a wide geo- graphical distribution. It is present at Stations D. 4174 and H. 4508, at the latter with JIaplophragmium scitulum , which the above some- what resembles. a Jones, Parker, and Brady, Monograph, Foram. Crag, 1866, p. 26.

At five stations where this species was dredged by the Challenger in the North Atlantic the depths with but one exception were be- tween 1,000 and 2,435 fathoms. Similarly three stations in the 132 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. Pacific were in depths of 95, 2,050, and 2,900 fathoms respectively. The species is therefore a deep-water form.

BIGENERINA ARENACEA Bagg, new species. Test very large, sometimes measuring nearly an eighth of an inch in length, strongly compressed and complanate, built of coarse arena- ceous and glauconitic material of a preA^ailing gray color. The segments are at first biserial, later nodosarian. There are four or five of these uniserial segments and they comprise about one-half the shell in length. The test is symmetrically developed Avith nearly straight even sides obtusely rounded and Avith the aboral end broadly rounded, the entire form resembling in a general way Bigenerina pennatula (Batsch), but lacking the angular keeled margin and also being somewhat more compressed. The segmentation is regular, much more regular than in Bigeneria capreolus (d’Orbigny), and in the uniserial portion is as symmetrical as in typical Frondicularia types. The chambers are narrow and even, separated by broad thick slightly raised septa which are curved or arched upward at the center and at the oral end form a wedge-shaped extremity. The aperture is a median, oval, and narrow slit. The best specimens of this large arenaceous species were from stations betAveen D. 3900 and I). 4000. (See Plate V, figs. 4-6.) The type is Cat. No. 8196, U.S.N.M., from hydrographic Sta- tion 4508, Albatross. I also recognize the species at Stations D. 4174 and H. 4566. Genus PAVONINA. PAVONINA FLAB ELLI FORM IS d’Orbigny.

With its limited number of triserial segments and its long textu- larian development, the above species might easily be mistaken for one of the Textularia. It was dredged by the Challenger at four stations at moderate depths and from both Atlantic and Pacific oceans. The fossil forms described by Berthelin were from the Gault of northern France. Not common at Station H. 4568. GAUDRYINA PUPOIDES d’Orbigny. Gaudryina pupoides d’Orbigny, Mem. Soc. Geol. France, IV, 1840, p. 44, pi. iv, figs. 22-24. This common deep-water variety is a frequent Cretaceous fossil and is not rare in some Eocene and later Tertiary deposits. Found at Stations H. 4430, H. 4555, H. 4568, and H. 4571. GAUDRYINA QUADRANGULARIS Bagg, new species. The test is very large, measuring about one-eighth inch in length, sharply tapering to a trihedral distal end. The oral extremity is quadrangular in outline, resulting from compression upon two sides, and this compression does not correspond with any of the triangular portion below. The shell substance is unusually coarse and the sur- face very rough. The oral end is abruptly truncated and is sunken in the center to the straight slit-like aperture somewhat protected by a marginal thickening and slightly notched. (See Plate V, fig. 1.)

With Haplostiche soldanii , which it resembles, this species is found in the coral sands of tropical waters. The two are separable by their difference in aperture, Clavulina cylindrica always having a valvular opening, while the other is always simple or perforate. Abundant in the Clavulina-szaboi strata of Hungary and also from the Tertiary of Italy. Rather rare in the South Atlantic, less so in the North Atlantic, and variously recorded in shoal waters of the South Pacific. Rare in the Globigerina ooze of Station D. 4000. Subfamily BULIMINmAl. Genus BULIMINA. BULIMINA AFFINIS d’Orbigny. Bulimina affinis d’Orbigny, Foram. Cuba, 1839, p. 109, pi. ii, figs. 25, 26. Equivalent probably to Reuss’s Bulimina ovulum , described in Cretaceous deposits and present in the North and South Pacific oceans of to-day. It is separated from B. ovata , which it closely re- sembles, only by its acute apical aboral extremity. Some specimens obtained from Stations D. 4017, D. 4025, and D. 4174. D'Orbigny obtained his types from the shore sands of Cuba. Dis- tribution much more limited, however, than that of the types of B. ovata and B. pupoides , which it resembles. BULIMINA ACULEATA d’Orbigny. Bulimina aculeata d’Orbigny, Ann. Sci. Nat., VII, No. 7, 1826, p. 269. With the smooth upper portion of the test and the lower rough spinous portion, the above is one of the peculiar surface ornamenta- tion forms found among the Buliminse. The spines often project from the edges of the chambers as in B. marginata , but in the former they are never lengthened into spines. Abundant in the North Atlantic and South Pacific and its bathymetric range extends from shallow depths down to 2,740 fathoms. It has been recognized in the glacial clays of Norway.

Said to affect moderately deep water; Professor Brady reports it as abundant in the North Atlantic, rare in the South Atlantic, and common in the South Pacific. Not recorded from the North Pacific. Ranges from less than 100 down to over 2,000 fathoms. Occurs at Station H. 4568, where it is not rare, and at Station H. 4585. BULIMINA CONTRARIA (Reuss). Rotalina contraria Reuss, Zeitschr. dentsch. geol. Gesell., Ill, 1851, p. 76, pi. v, fig. 37. It is no wonder that this little form has been described under va- rious genera — such as Ataxophragmium , Pulvinulina , and Cassidu- lina — for it possesses marked similarity of growth to all the above. It has, however, been rightly placed among the Bulimince , and its aperture alone justifies this as well as its buliminine method of growth. Most common in shoal waters of the South Pacific, but also known in the North Pacific and the North Atlantic. Present at Stations D. 4000, H. 4430, and H. 4555.

BOLIVINA ^NARIENSIS (Costa). Brizalina wnariensis Costa, Atti dell’ Accad. Pontin., VII, 185G, p. 207, pi. xv, figs. 1, a, 1). This neatly tapering, striate Bolivina , with or without its spinous aboral end, is cosmopolitan, and we found it at Stations D. 4174, H. 4440, H. 4502, H. 4508, H. 4555, H. 4567, H. 4571, H. 4585, and H. 4696. Best developed types come from the North Atlantic Ocean at depths of a few fathoms down to 1,630 fathoms. Professor Brady records the species from off the Philippines at 95 fathoms, off the south coast of Japan at 15 fathoms, and the La Plata River, South America, at 18 fathoms. It occurs as a fossil in the Tertiary beds of the island of Ischia. BOLIVINA DILATATA Reuss. Bolivina dilatata Reuss, Denksclir. Akad. Wiss. Wien, I, 1849, p. 381, pi. xlviii, fig. 15. The test of Bolivina dilatata is broad, depressed, composed of numerous long narrow chambers and possessing an acute periphery. Prof. H. B. Brady states that the species is confined to the North Atlantic, but we find it present, and in some cases abundant, at nearly every station studied. These are : D. 4017, D. 4025, D. 4174, H. 4430, H. 4502, H. 4508, H. 4555, H. 4568, H. 4571, H. 4694, and H. 4696. The average depth is below 400 fathoms. The geological occurrence dates from the Cretaceous. BOLIVINA HANTKENIANA Brady. Bolivina hantkeniana Brady, Quart. Journ. Microsc. Sci., XXI, n. s., 1881, p. 58. Test depressed and nearly equally convex on each surface, con- sisting of numerous broad inflated segments arranged alternately and provided at their margin with a delicate keel. The surface is usually faintly striate. Probably limited in distribution to islands of the Pacific. Present at Station D. 4017, fine specimens at H. 4440, also found at H. 4555 and H. 4585. The depths at which the form is recorded vary from 130 to 800 fathoms. Not recorded as a fossil. 138 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. BOLIVINA KARRERIANA Brady. Bolivina karreriana Brady, Quart. Journ. Mjcrosc. Sc*i., XXI, n. s., 1881, p. 58. This interesting little species is said to be abundant in the waters south of Japan, and it is not uncommon in the South Pacific. Found only at Station H. 4567, where it was quite rare. BOLIVINA LIMBATA Brady. Bolivina limbata Brady, Quart. Journ. Microsc.

Thirteen of the twenty- two localities given in the Challenger re- port, where the above species is found, were in the South Pacific. Abundant at some stations and present at D. 4025, II. 4555, H. 4566, H. 4568, H. 4571, and H. 4585. The species is generally confined to shallow waters, but in one instance it was obtained at 1,900 fathoms in the South Atlantic. A. Goes considers this form only a variety of B. dilatata , but I believe it should be regarded as a distinct species. BOLIVINA SEMI-ALATA Bagg, new species. The nearest approach to this Foraminifer of which the writer has knowledge is Bolivina hantkeniana. The forms we have, however, are extremely narrow and stoutly built, with numerous chambers extending to nearly one-half the length of the shell. The ultimate chambers are exceedingly broadly expanded and widely keeled, the flange extending even over and around the aperture. The lower end is acuminate. Two of these types were observed at Station IT. 4555. The shell is large for the genus Bolivina. (See Plate V, fig. 3.) Type. — Cat. No. 8197, U.S.N.M., Station H. 4555.

More important from the fossil standpoint than any Bolivina unless perhaps B. punctata , and widely represented in existing seas. Its bathymetric range is also very extensive, but it is best developed on shallow bottoms. It is one of the best known Cretaceous Boli- vinas. Found at Stations H. 4017, fine examples at H. 4025, also present at H. 4430, H. 4440, H. 4508, H. 4566, H. 4568, H. 4585, H. 4694, and H. 4696. Subfamily CA.SSI!DTT:LIlNri]NrJE:. Genus CASSIDULINA.

Characterized by its obtuse periphery, oval outline, and small number of short inflated segments, which distinguishes the species from C. laevigata. Common over wide areas in the North Atlantic and at depths as great as 2,760 fathoms. A long list of localities given by Professor PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. 140 Brady in the Challenger report includes numerous localities in the North and South Pacific and the South Atlantic, and the form is present in the Mediterranean.

Sci., XXI, n. s., 1881, 1). 60. “ Test subglobular, somewhat compressed on the two lateral faces, inequilateral; segments few, slightly inflated; alternation irregular. Aperture an oblique or nearly erect loop-like slit on the face of the projecting terminal segment.” 0 Essentially a deep-water species, the above is known from all the large oceans, but the localities are not very numerous. Found at three Albatross stations, namely, H. 4430, H. 4571, and H. 4585. Genus EHRENBERGINA. EHRENBERGINA SERRATA Reuss. Ehrenbergina serrata Reuss, Denkschrift, Akad. Wiss. Wien, I, 1849, p. 377, pi. xlviii, figs. 7 a-c. The genus Ehrenbergina is closely related to C assidulina, but dif- fers in the arrangement of the biserial chambers and less inrolled growth. Cassidulina has the segments both biserial and convolute, and resembles a bolivine shell longitudinally folded and then rolled in this suture from end to end and possessing a bulimine aperture. The typical species of Ehrenbergina are longer than Cassidulina and the margins are frequently serrate or spinous. Living representatives of the genus belong to southern oceans, and the bathymetric range is from several to over 2,000 fathoms. This species is well known from the Miocene. We find it rather abundant at several stations — H. 4430, H. 4476 (common), H. 4567, H. 4694, and H. 4696. Family LAGENIDiE. Subfamily LAGENIN^l. Genus LAGENA. LAGENA FAVOSO-PUNCTATA Brady.

Lagena hispida Reuss, Zeitschr. deutscli. Geol. Gesell., X, 1858, p. 434. The test of Lagena hispida varies in shape, but always shows a his- pid surface, which is its distinguishing characteristic. Like the preceding, this species has a long geological history, dating from the Lias. In recent waters it is not limited in distribution or depth, but it is not abundant wherever found. Present at Station H. 4585. LAGENA LiEVIS (Montagu). Vermiculum Iceve Montagu, Test. Britain, 1803, p. 524. One of the simplest unornamented unicellular hyaline Foraminif- era. On account of its variability in form it has been described under many names, a long list of which is given in any complete synonymy of the species. It is unquestionably one of the earliest Foraminifera known, occurring in Upper Silurian deposits. Its distribution and bathymetric range are unlimited at the present time.

Professor Brady records the above variety of the typical A", con - sobrina at depths of from 290 to 725 fathoms in the North Atlantic and 350 fathoms in the South Atlantic; in the South Pacific from 129 to 1,375 fathoms.

Men., 1846, p. 49, pi. ii, figs. 11-14. This species must not be confounded with Nodosaria guttifera (Parker and Jones), which is unquestionably to be regarded as Nodosaria soluta. In the form figured by d’Orbigny in the Vienna Basin memoir the segments of Nodosaria guttifera are gracefully oval, bulbous at base and connected to the next succeeding chamber by a very slender neck. In Nodosaria soluta the segments are smooth and the distal chamber usually mucronate, but the segments are more closely joined and the sutures are not as deeply depressed or constricted as in Nodosaria guttifera. Fragments only at Station H. 4566. NODOSARIA LiEVIGATA (d’Orbigny). Glandulina Icevigata d’Orbigny, Ann. Sci. Nat., VII, 1826, p. 252, pi. x, figs. 1-3. There appear to be three well-defined types of N odosarice belong- - ing to the Glandulina type, best represented by Nodosaria laevigata with its sharp distal and generally mucronate and its relatively large development of the ultimate chamber; second, the form Nodosaria votundata , with its more bluntly rounded nonspinous primordial margin and slightly greater elongation of the chambers; and third, Nodosaria aequalis , with its still greater elongation and wider seg- ments. Some of the specimens we find in the three stations, D. 4025, H. 4555, and H. 4696, are not distinctly mucronate but they are decid- edly pointed at the distal end and may better be considered as varieties of this exceedingly varied species. The relationship of the various types belonging to this group are well described by Professor Reuss in his paper on Von Schlicht’s drawings of Tertiary Foraminifera.® The distribution of the species is world-wide. Its bathymetric range is generally less than 1,000 fathoms. ° Sitzungsber. Akad. Wiss. Wien, LXII, p. 478. 144 PROCEEDINGS OF THE NA TIONAL MUSEUM VOL. XXXIV. NODOSARIA PAUPERATA (d’Orbigny).

Professor Brady ob- served it at only two localities, one near Ki Islands, 129 fathoms, the other on the coral reefs of the Hawaiian Islands, 40 fathoms. The form is characterized by its robust test, with surface strongly costate, but less regularly so than in Nodosarice. Genus RHABDOGONIUM. RHABDOGONIUM MINUTUM Reuss.

This species was described by Reuss in 1870 under the genus Cris- tellaria, although he had previously placed it under the genus Robu- lina , a name now in disuse. The shell is stoutly built, thicker and with more angular margin than Cristellaria rotulata. There is also a smaller number of segments in typical specimens. “ Fine examples of Cristellaria articvlata occur in the dredged sands from off Culebra Island, 390 fathoms, and off Nightingale Island, Tristan da Cunha, 100 to 150 fathoms. In the latter locality the species is very abundant, and what is more remarkable the species assume wild-growing forms, such as are represented by figs. 1-4, pi. lxixT® Found by the writer in the New Jersey Cretaceous and vari- ously recorded in Tertiary deposits. Cristellaria are not abundant in any of the material we have here studied, but there are as many spe- cies represented as there are occurrences.

Compare ref. in Goes, Kongl., Svenska, Vtenskaps Akad. Handl. XXV, No. 9, p. 64. I think I am right in ascribing to the above species the form de- scribed below. The test is much compressed and rather strongly striate with smooth ultimate chamber slightly prolonged. The out- line is quadrangular and the periphery bluntly rounded without keel. There are about seven chambers visible in the last convolution, the inner ones but faintly visible, the latter clearly marked by the slightly depressed septa. The aperture is fissurine, somewhat prolonged but not tubular. The shell we find of a grayish-white color and large for the genus. In general growth the test strongly resembles Cristellaria crepidula , but it is more stoutly built, and there is a difference in the method of extension of the chambers forming the last convolution. There is a figured form of Cristellaria in Professor Williamson’s Monograph on the Recent Forminifera of Great Britain which roughly resembles the present form (fig. 55, pi. n), but the latter is provided with a well-defined flange. Present at Station II. 4508 of the Albatross. Our one specimen is comparable to the figured specimen of A. Goes.® CRISTELLARIA GIBBA d’Orbigny. Cristellaria gibba d'Orbigny, Foram.

TORAMINIFERA FROM THE HA W A II A N ISLANDS— BA G G. 151 UVIGERINA CANARIENSIS var.. STRIATA Bagg, new subspecies. Notwithstanding that Professor Brady has mentioned the fact that some forms of Uvigerina canariensis are very weakly striated in their lower portion and that such forms are synonymous with d’Orbigny ’s Uvigerina urnula , I find at Station 4566 a form which has definite striations extending in groups clear and well-defined, though not closely set down, and over the last chamber as well as over the earlier segments as in Uvigerina pygmcea. The inflation of the segments is marked and the septa are depressed. This form seems to be suf- ficiently marked to be considered distinct, although Professor Brady has treated such specimens as varieties only of the more widespread type, Uvigerina canariensis .

SAGRAINA IRREGULARIS Bagg, new species. Test elongate with irregularly set stout segments separated by septa which are but little depressed, giving a nodosarian aspect to the shell. The distal end is narrowly rounded without being acuminate, the anterior abruptly truncated with an invaginated siphonal tube at the end of which is the circular flaring aperture. This peculiar inset effect of the apertural tube, together with the irregularly set cham- bers, affords a ready means of separation of the form from Sagraina striata Schwager, which the species somewhat resembles. The stria- tions of the surface are sinuous, delicate and fairly persistent, but they branch in some places. The texture of the shell is fine semitrans- lucent hyaline calcareous matter and the tests are rather large and well built for the genus. Found in material from Stations D. 4025 and H. 4571 and common at the former station. (See Plate V, figs. 8 - 10 .) Type. — Cat. No. 8200, U.S.N.M., Station 4025.

This symmetrically but loosely built Globigerina is one of the most abundant forms in all the material dredged in the 19 stations we examined. The forms are large and beautiful and in various stages of growth. This is less common perhaps than Globigerina bulloides , but is of larger size. Not likely to be confused with G. cretacea. which is more involute, trochoid in its growth, and less common.

Globigerina dubia Egger, Neues Jahrbuch fur Min., 1857, p. 281, pi. ix, figs. 7-9. “ The Globigerina dubia of Egger can only be accepted as a va- rietal modification of Globigerina bulloides , representing perhaps the best development of the typical characters. The test attains somewhat larger dimensions, is stout and compactly built, distinctly rotaline in general conformation, and with a well-marked umbilical cavity. It lias frequently as many as fourteen or fifteen segments. Pelagic specimens of this variety have been taken in the South Atlantic and in the North and South Pacific; and in bottom ooze it has been found also in the North Atlantic. Its northern limit appears to be about latitude 56" north, a little to the south of the Bockhall Bank; whilst in the opposite hemisphere it reaches as far as about latitude 46° south in the Southern Ocean.” a Doctor Egger’s fossils were from the Miocene of Bavaria.

Differs from A. ammonoides in the greater compression of the test and the more squarely built periphery, together with a stronger limbation of the sutures. Widely found in the North Atlantic, at moderate depths; rare in the South Atlantic, and also the South Pacific ; abundant in the Med- iterranean. Found also at the Abrohlos Bank from 47 to 940 fathoms, and in Hongkong Harbor. In the fossil state it is known from the Cretaceous, and has been found in the Tertiary and later deposits in many localities. Bather rare at Stations H. 4430 and H. 4567. ANOMALINA CORONATA Parker and Jones. Anomalina coronata Parker and Jones, Ann. Mag. Nat. Hist., ser. 2, XIX, 1857, p. 294, pi. x, figs. 15, 16. The above species is coarsely constructed, like Anomalina grosseru- gosa , but the segments are more or less angular along each side of the peripheral border and sharply marked off from the depressed umbilici. The perforation of the shell is coarse and the test large. Rare within the Tropics but abundant in many temperate zone dredg- ings from the North and South Atlantic oceans. Geologically known from the Eocene through the later Tertiaries. It is usually found 160 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL.

Perhaps the largest and most typical are from Station H. 4566. ANOMALINA GROSSERUGOSA (Gumbel). Truncatulina grosserugosa Gumbel, Abhandl. d. k. bayer. Akad. Wiss., II, Cl. X, 1868, p. 660, pi. n, figs. 104, a, 1). Resembles Anomalina ammonoides , but is larger, more stoutly built and has only a few chambers in the last convolution. The perfora- tion is coarse but there are fewer pores upon the superior surface. The Challenger expedition obtained this form from only a few lo- calities in the North and South Atlantic and in the North and South Pacific. The depths were from 345 to over 2,000 fathoms. I am inclined to think, however, that it is much more common than these results would indicate. I find excellent specimens at Station D. 4502 and it is present at the following localities: Stations D. 4174, H. 4430, H. 4440, H. 4502, H. 4508, H. 4555, H. 4571, and H. 4696. I have recorded the form in the New Jersey Cretaceous and it has been variously recorded in the European Tertiary. A very similar form is found in the Vienna basin Miocene near Baden, and de- scribed by d’Orbigny under the name Anomalina badenensis ANOMALINA POLYMORPHA Costa. Anomalina polymorpha Costa, Atti dell’ Accad. Pontan., VII, 1856. p. 252, pi. xxi, figs. 7-9. A large coarsely built form with extensions of the chambers at the periphery irregularly into stout spines. The perforation is very large and the pores few, and the species is somewhat like Anomalina grosserugosa , but is less thick. It is considered isomorphous with Rot alia calcar and Pulvinulina spinimargo. Present at shallow depths in both Atlantic and Pacific oceans. Recorded by Costa from the Miocene of Italy.

One of the most beautiful of all Pulvinulina^ and of very large size. It is a comparatively shallow-water type, while its related form, Pulvinulina partschiana , is a deep-water species. Found rather abundant at Stations D. 4174, H. 4430, H. 4502, H. 4508, H. 4555, H. 4567, H. 4571, H. 4585, and H. 4696. PULVINULINA GILBERTI Bagg, new species. From the dredging of Station 4567 I find two specimens of Pulvi- nulina which appear to be new. The test is highly vaulted upon the inferior side, with deeply sunken septa which extend from the mar- gin to the umbilicus in an almost straight line, as in Pulvinulina canariensis d’Orbigny, which this species somewhat resembles. The segments are, however, more compactly built and the aperture, a neatly shaped arch, lies midway between the periphery and the umbilicus upon the inferior surface. The superior surface, instead of being vaulted as in P. canariensis , is almost complanate and the periphery is almost keeled, being quite sharp and distinct, although somewhat lobulated on the last two chambers of the ultimate whorl. There are five segments visible in the last convolution and they are equally dis- tinct upon both surfaces. (See Plate V, figs. 11-15.) The shell is very minute and firmly built. It has a slight resem- blance to Truncatulina dutemplei (d’Orbigny), but the margin is sharp and more angular in the present form, and the septal lines upon the inferior surface are much more depressed and the chambers more inflated. It is somewhat doubtful whether the present form should be considered a distinct species or only a variety of Pulvi- nulina menardii , which it resembles. It is much smaller than P. me- nardii , much more vaulted upon the inferior surface, and a little more closely involute. The septal depressions also are strong, deeply sunken on the lower side, and extend straight to the center. Upon the superior side they are strongly curved as in P. menardii. There are five of these chambers in the final convolution. The ultimate chamber is largest and in its outline reminds one of the auriculate Proc. N.

Brady in the Challenger Report (p. 686) writes that with the exception of one occurrence near the west coast of Patagonia the species is limited to the North Atlantic, and we may be wrong in placing the few specimens we have under this species. The characters agree tolerably well, however, and the identification may be conditionally made as above. PULVINULINA REPANDA (Fichtel and Moll). Nautilus repandus Fichtel and Moll, Test.

I think I am right in placing the small Nonionina found at Station H. 4566 in this species. The form resembles Nonionina pompilioides in outline, but the former has more segments, thicker umbilici, and less regular arrangement of the segments. This species has been dredged off the cold waters of Spitzbergen, off the Canaries, off Pata- gonia, and elsewhere, but at very shallow depths. It is obtained in the Eocene and later Tertiary of Europe. Station H. 4566. NONIONINA POMPILIOIDES (Fichtel and Moll). Nautilus pompilioides Fichtel and Moll, Test.

The elongate oval segements and depressed chambers which rapidly eidarge from the umbilicus make the form easily recognizable. Fre- quent in dredgings from many regions and common as a fossil in the Tertiary. It does not appear to be limited in depth. Stations D. 4000, D. 4025, H. 4440, II. 4567, and H. 4696 afford specimens of this species. It appears to be the most common Nonionina in our dredgings. no. 1603.

Nat., VII, No. 3, 1826, p. 304, pi. xvii, figs. 1-4. The recent types of Amphistegina are very difficult to separate even in varieties on account of the great variation of form they exhibit. Professor Brady a separates the species Amphistegina lessonii into three divisions, namely: (1) compressed lenticular form A. vul- garis Parker, Jones, and Brady), (2) thick variety, more often in- Challenger Report, IX, p. 740. PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. 166 equilateral ( —A. gibbosa Williamson), and (3) thick forms, still more inequilateral ( =A. rugosa d’Orbigny). In the material studied there are two well-developed types; one rather small, shin- ing, white, nearly equilateral, moderately vaulted, with all the seg- ments visible in the final volution, the other very gibbous, opaque, larger than the first, with some granulations around the aperture near the margin, with the chambers uniformly curved, and without the sinuosity of the smaller types. It is possible that this second form represents a new type, but since so much latitude has been granted the original A. lessonii I prefer to consider these two types as one and refer to the average symmetrical form as A. lessonii and the other as the globose variety. The species is unusually abundant in the Hawaiian dredgings. It was recognized in the following stations of the 19 examined: D. 4000, D. 4025, D. 4174, H. 4430, H. 4440, H. 4476, H. 4508, H. 4566, H. 4567, H. 4579, and H. 4694. The typical globose type is abundant at Station 4476. Abundant in the tropical waters of the great oceans. It is best de- veloped on bottoms of less than 30 fathoms, and is rare below 400 fathoms.

Like Haplostiche , this genus has but a single living representative. It is a shallow-water tropical form found around many coral islands.- But two specimens of this well-known species were obtained at Station H. 4566. Genus NUMMULITES. NUMMULITES CUMINGII Carpenter. Amphistegina cumingii Carpenter, Pliil. Trans., 1859, p. 32, pi. v, figs. 13-17. The classification of recent Nummulites is to the mind of the writer in an entirely unsatisfactory condition. The difficulty has come from considering under one species many marked varieties with not only more chambering in each volution but also from a difference in vault- ing or thickness of contour, which results in altering the entire figure of the shell. Under Amphistegina were mentioned several varieties, and the same might be done with the Nummulites series. The mul- tiplication of chambers, however, is, I think, important and a form with twice the segmentation in a given whorl ought not to be re- garded as belonging to a species with only one-half as many. Again the asymmetry of the test is one of the chief features which serve to distinguish the genus Nummulites from Amphistegina , and even Carpenter later referred the present form to Nummulites after NO. 1G03. FORA M INIFERA FROM THE HA WAIIAN ISLANDS— BAGG. 167 previously classifying it with Amphistegina. However that may be, there is a considerable amount of variation among these forms which in the fossil state would be sufficient to cause their separation into several species or at least important varieties of the typical form. This matter can not be properly entered into here, but we have pur- posely kept Nummulites radiata separate from Nummulites cumingii , notwithstanding that it is considered synonymous by Prof. H. B. Brady. The species Nummulites cumingii is confined to tropical and sub- tropical latitudes and is found only in very shallow Avaters. In speci- mens from Station D. 4000 there are fourteen chambers in the final convolution. In Nummulites radiata the number is much greater (nearly double), and they are more sinuous. Also the shell is of a dark brown color in Nummulites radiata and somewhat smaller. Stations D. 4000, H. 4476, H. 4566 (?), and H. 4590. Not as abun- dant as Amphistegina at any of the above stations. NUMMULITES RADIATA d’Orbigny. Nummulina radiata d’Orbigny, Foram. Foss. Vien., 1846, p. 115, pi. v, figs. 23, 24.
