Mammals -- North America
Kellogg (Proc. U.S. Nat. Mus., 86:253, February 14, 1939) tentatively
referred specimens of the short-tailed shrew from the mountainous parts
of eastern Tennessee to the subspecies _Blarina brevicauda talpoides_,
with the remark that they were unlike specimens of that subspecies
obtained in eastern and southern West Virginia. Subsequently, Bole and
Moulthrop (Sci. Publ. Cleveland Mus. Nat. Hist., 5:109, September 11,
1942) named the subspecies _Blarina brevicauda churchi_ with type
locality at Roan Mountain, North Carolina. We have examined the
specimens in the U.S. National Museum recorded by Kellogg (_loc. cit._)
from the following localities: Shady Valley, 2900 ft. (Catalogue No.
267182); Holston Mtn., 4 mi. NE Shady Valley, 3800 ft. (Nos.
267176-267178, 267180, and 267181); Holston Mtn., 3 mi. NE Shady
Valley, 3000 ft. (No. 267179); Roan Mtn., (Nos. 267469-267475); Mt.
Guyot, 6300 ft. (No. 267183); 4-1/2 mi. SE Cosby, 3300 and 3400 ft.
(Nos. 267184 and 267185); and Snake Den Mtn., 3800 ft. (No. 267186).
Among named kinds of _Blarina brevicauda_, we find these specimens to
resemble most closely _Blarina brevicauda churchi_ and so refer them.
They are readily distinguishable from specimens of _B. b. kirtlandi_,
that occurs farther north in the same mountain range, by larger size
and longer tail. Incidentally, in the specimens that we have examined,
we do not find that _B. b. churchi_ is darker colored than other
subspecies of _Blarina brevicauda_; _B. b. churchi_, to us, is
indistinguishable in color from _B. b. kirtlandi_. Bole and Moulthrop
(_op. cit._) thought that _B. b. churchi_ was notably darker than other
subspecies from adjoining areas.
~Blarina brevicauda carolinensis~ (Bachman)
Blair (Amer. Midland Nat., 22(1):99, July, 1939) referred specimens of
the short-tailed shrew from the Arbuckle Mountain area of Oklahoma to
_Blarina brevicauda hulophaga_ and specimens from Mohawk Park, Tulsa
County, Oklahoma, to _B. b. carolinensis_. Later Bole and Moulthrop
(Sci. Publs. Cleveland Mus. Nat. Hist., 5:108, September 11, 1942) saw
two of the specimens from Mohawk Park and assigned them to _B. b.
hulophaga_. According to the most recent published account, therefore,
_B. b. hulophaga_ would seem to have a peculiarly discontinuous
geographic range. We have examined the material seen by Blair and by
Bole and Moulthrop (Nos. 75946, 75947, 75643, Mus. Zool. Univ.
Michigan) in an attempt to form our own judgment as to their
subspecific identity. The teeth of No. 75946 are well worn, whereas the
teeth of the other two are scarcely worn. We are unable to distinguish
No. 75946 from topotypes of _B. b. carolinensis_ by size, color, or
cranial features. The two younger specimens are smaller and paler, but
do not agree with the description of _B. b. hulophaga_. The
nearly-complete narrow, white girdle of No. 75947 is clearly an
individual variation. We assign the animals to _Blarina brevicauda
carolinensis_ (Bachman) as did Blair (_loc. cit._).
