TWO ADDITIONS TO THE MAMMALIAN FAUNA OF MICHIGAN
THE northern pine vole, Microtus pinetorum
scalopsoides (Audubon and Bachman) has ap-
parently not been recorded from Michigan,
and up to last year no Michigan specimen had
been secured by the museum. In April, 1912,
a specimen (No. 42,558, Museum of Natural
History, University of Michigan) was taken
by W. A. Brotherton, near Rochester, Oak-
land County, and since that time the writer
has examined two specimens from the collec-
tion of the Michigan Agricultural College,
both of which were secured near East Lansing,
one on April 20, 1901, by D. S. Bullock, and
the other in August, 1896, by T. L. Hankin-
SOIl.
Another species apparently new to the Mich-
igan fauna is Richardson’s shrew, Sorea:
richardsonii Bachman, a specimen of which,
taken at Chatam, Alger County, August 28,
1900, is in the collection of the Michigan
Agricultural College. Although Seton' in-
cludes the northern peninsula in his map of
the range of the species, the writer can find
no recorded localities nearer than Oneida
County, Wisconsin,” and the north shore of
Lake Superior. Northern Michigan has prob-
ably been included in the range hecause this
region formed a part of the “Northwest
Territory"; it is not included by Merriam."
The museum is indebted to the U. S. Bio-
logical Survey for verifying the identifica-
tion of the specimens mentioned, and to Pro-
fessor W. B. Barrows, for the loan of the
specimens in the Michigan Agricultural Col-
lege. NORMAN A. WOOD
