ntified as
_Thomomys talpoides clusius_ two specimens (66465 and 66523 BS) from
Pass (= Parkman) and one specimen (66464 BS) from Dayton, in Wyoming. We
have examined these specimens and find that they lack the broad
braincase and narrow nasals of _clusius_ and in these and in other
features the three specimens resemble _T. t. caryi_ and _T. t. bullatus_
more than they resemble any other named kinds. Although structurally,
and in color, intermediate between the two subspecies named immediately
above, the specimens show greater resemblance (large size and narrow
braincase) to the latter and are referred by us to _Thomomys talpoides
bullatus_.

~Thomomys talpoides clusius~ Coues

Bailey (N. Amer. Fauna, 39:102, November 15, 1915) identified as
_Thomomys talpoides bullatus_ an adult male (147347 BS) from the J. K.
Ranch, 5900 ft., on Meadow Creek, Wind River, Wyoming [= Wind River of
Bailey, _loc. cit._] and a young female (168666 BS) from Sage Creek, 8
mi. NW Fort Washakie, Wyoming. The rosaceous tone of these pale
individuals is more as in some populations of _T. t. ocius_ and _T. t.
clusius_ to the southward. Also, the skull of the male, although large,
is distinctly narrower than in _T. t. bullatus_ and we think shows the
influence of the _T. t. tenellus_ stock. All features considered, we
refer the specimens to _T. t. clusius_.

~Thomomys talpoides glacialis~ Dalquest and Scheffer

Vernon Bailey (N. Amer. Fauna, 39:119, November 15, 1915) listed 19
specimens from Roy, Washington, as _Thomomys douglasi yelmensis_
Merriam. Our examination of 26 specimens (205039-205051, 205072-205077,
and 206545-206551 BS) labeled as "Roy," and presumably including those
listed by Bailey (_loc. cit._), leads us to identify all 26 as _Thomomys
talpoides glacialis_ on the basis of widely spreading zygomatic arches
and decidedly ochraceous hue of underparts.

~Geomys bursarius jugossicularis~ Hooper

Seven skins with skulls (35104/47369-35110/47375 BS) from Las Animas,
Colorado, probably formed the basis for Cary's (N. Amer. Fauna, 33:129,
August 17, 1911) record of _Geomys lutescens_ from that locality.
Comparison of the material reveals that the animals are referable
instead to the later named subspecies, _Geomys lutescens jugossicularis_
Hooper (Occas. Papers Mus. Zool., Univ. Michigan, 420:1, June 28, 1940),
on the basis of (1) more reddish color, (2) deeper zygomatic plate, (3)
shorter jugal as expressed as a percentage o
