Comments on the Taxonomy and Geographic Distribution of Some North American Rodents

Howell (Jour. Mamm., 13:166, August 9, 1932) referred two specimens from
Boone County, Indiana, to _T. s. fisheri_. We have examined a specimen
(5675 AMNH) from that place and think it is one of the two seen by
Howell. The specimen is a poorly made skin in worn winter pelage with
the skull inside. Because it differs from _T. s. fisheri_ and agrees
with _T. s. ohionensis_ in the color of both upper parts and underparts
(comparisons made with material of comparable stage of molt), we assign
it to the latter subspecies. Howell (_loc. cit._) referred specimens
from Overton (57394), Wooster (57398, 57399, and 57442), and Loudonville
(57391-57393), all from Ohio, in the Museum of Zoology of the University
of Michigan, to _Tamias striatus fisheri_. We have examined these
specimens and find them to be readily separable from _T. s. rufescens_
on the basis of darker coloration. The affinities of the specimens in
question are with _T. s. fisheri_ and _T. s. ohionensis_. As a standard
for comparison we have used specimens in the Museum of Zoology,
University of Michigan, in comparable pelage of _T. s. ohionensis_ from
Dearborn County, Indiana, taken in August and specimens of _T. s.
fisheri_ from "near" summit Butt Mtn. and Little Meadows, both places in
Giles County, Virginia, as well as two specimens from Allair, Monmouth
County, New Jersey. On the basis of buffy (instead of white) edging of
the tail, buffy (not white) light dorsal stripes, and buffy (not black)
anterior third of the median dark stripe, the specimens from Overton,
Wooster, and Loudonville are referred to _Tamias striatus ohionensis_.

A. H. Howell (N. Amer. Fauna, 29:16, November 30, 1929) recorded six
specimens of _Tamias striatus striatus_ from Greensboro, Alabama.
Subsequently, Lowery (Occas. Papers Mus. Zool., Louisiana State Univ.,
13:235, November 22, 1943) named _T. s. pipilans_ and assigned to it
specimens from northeastern Alabama. Lowery did not, however, mention
the specimens from Greensboro and, thus, their subspecific identity was
placed in doubt. We have examined five of the six specimens mentioned by
Howell (_loc. cit._) (57034-57036, 57588, and 77037 BS) and because of
their brilliant color and large size, refer them to _Tamias striatus
pipilans_ Lowery.
