The series consists of nine volumes, viz. –The Catalogue of Batrachia Salientia, published in 1882; the Catalogue of Batrachia Gradientia, also in 1882 ; the Catalogue of Lizards, vol. i. 1885, vol. ii. 1885, vol. iii. 1887; the Catalogue of Chelonians, Rhynchocephalians, and Crocodiles, 1889; and the Catalogue of Snakes, vol. i. 1893, vol. ii. 1894, and vol. iii. 1896. - These works are not only catalogues in the ordinary sense of the largest general collections of Batrachia and Reptilia ever yet brought together, but are complete monographs of the groups of animals treated of, so far as their zoological characters, geographical distri- bution, and synonymy are concerned—descriptions being given of every species regarded by the author as valid, whether contained in the Museum or not. - - The initiative of the series is due to Dr. Günther. It was begun and has been carried out almost to its close under his Keepership of the Zoological Department. - Of the unremitting devotion of Mr. Boulenger to the task which has occupied him for more than fifteen years, or of the ability and iv PREFACE. large anatomical and literary knowledge he has brought to bear upon it, it is not necessary for me to speak—they are known to all, zoologists; and I hardly need point out that the value of the work has been greatly increased by the numerous carefully executed figures of new species and of illustrative anatomical details which it contains. W. H. FLOWER, Director. April 15, 1896. INTRODUCTION. THIs concluding volume of the Catalogue of Snakes, contains the descriptions of 689 species, 564 of which are represented in the Collection, and the enumeration of 5230 specimens. The total number of recognized species of Ophidians now amounts to 1639. Duméril & Bibron’s ‘Erpétologie Générale’ (1854) registers 531; Gray and Günther's Catalogues (1849–58) 544; and 789 (including numerous nomina nuda) are enumerated in Jan's ‘Elenco’ (1863). The amalgamated index to the three volumes, which is appended, contains 7335 names, thus showing the enormous extent of the synonymy. With this volume the revision of the entire Herpetological Collection in the British Museum is brought to a close, a work the publication of which has extended over fourteen years. The whole series of Catalogues, consisting of nine Volumes—two of Batrachians (1882), three of Lizards (1885–87), one of Rhyncho- cephalians, Chelonians, and Crocodiles (1889), and three of Snakes (1893–96)—deals with 4,413 species and 28,642 specimens. But the numerous additions to the Collection and to the Literature, made since the appearance of the earlier volumes, raise these numbers as follows:– vi INTRODUCTION.

The Author begs to express his thanks to the following gentlemen who have assisted him in the preparation of the Catalogue of Snakes, through gift or loan of specimens, or with notes on the types in the Collections under their charge :-Professor Waillant, Dr. Moc- quard, and M. Bocourt, of the Paris Museum ; Marquis Doria and Dr. Gestro, Genoa; Professor Hertwig, Munich ; Professor Ehlers, Göttingen; Professor Barboza du Bocage, Lisbon ; M. Dollo, Brussels; Professor Möbius and Dr. Tornier, Berlin; Professor Boettger, Frankfort/M.; Professor Camerano and Count Peracca, Turin; Professor Bavay, Brest ; and Professor von Méhely, Eronstadt. To his former Chief, Dr. Günther, to whose initiative the publication of this work is due, his best thanks are also now offered for the kind encouragement he has bestowed on him for so many years. - G.

Soc. xxiv. 1887, p. 56, from Matto Grosso, Brazil, appears to agree in every respect with H. melanocephalum, except in having the first lower labial separated from its fellow by the symphysial. This is probably merely an individual variation, as the condition described by Cope is nearly attained by two of the specimens from Para in the Museum. * 2. Homalocranium annulatum.

The author has taken a conservative view in this case and provisionally maintained intact the association which has so long been known under the name of Naja tripwdians. It is never- theless advisable to recognize some of the forms as subspecies. A.

Characters of Callophis, except that the poison-glands, instead of being confined to the temporal region, extend along each side of the body for about one third of its length, gradually thickening and terminating in front of the heart with club-shaped ends. The presence of these glands may be detected without dissection by feeling the thickening and rigidity of the cardiac region in the second third of the body, the heart being shifted further back than in other snakes owing to the extension of the glands.

Thanks to the kindness of Prof. Hertwig, I have been able to examine the type specimen (6), from the R. Japura, preserved in the Museum of Munich. E. imperator, which is identified with E. batesii by Cope, forms a colour-variety distinguished by the spaces between the transverse series of yellow spots, on the back, being alternately black and red, the red ventral cross-bars extending to the upper surface. . 6.

Mandible without coronoid bone. Solid teeth in both Jaws. The hypapophyses disappear in the anterior third of the dorsal vertebral column. These Snakes, which inhabit South-eastern Asia and Central and South America, may be readily distinguished from the Colubridae, without an examination of the skull, by the absence of a mental groove, the mouth being susceptible of but slight expansion, and by the free termination of the pterygoid bones, which do not diverge behind, as may be seen on the back of the palate when the mouth is fully open.

This species may be divided into several ill-defined varieties, the two extremes being the var. wanthina, Gray, from Asia Minor and Syria, and the var. deserti, Anders., from the confines of the Tunisian Sahara—the former characterized by an obtusely pointed snout covered with strongly keeled scales, the latter with a very short and broad snout without canthus and covered with smooth scales. Certain specimens approach the var. hugyi of V. aspis, and the species is to a certain extent connected with V. russellii through the var. acanthina.

This species may have to be united with the following. The only character by which I have distinguished the two, viz., the length of the keel on the dorsal scales, is not dependent on age or sex, as had been supposed. Some specimens of L. lanceolatus, however, approach L. atroa, in the swelling of the scales at the 'base of the keels, and are thus intermediate between the two sup- posed species. It is also not impossible that two or three species are confounded here under L. lanceolatus, but I have been unable to trace any limits or to find any correlation between the modifications in scaling and coloration. 3.
