ddition, Swenk
(_loc. cit._), in the paragraph preceding the description of
_olivaceogriseus_, states that the holotype was actually taken on Little
Bordeaux Creek, sec. 14, T. 33 N, R. 48 W, 3 mi. E Chadron, on the farm
of L. M. Gates, who obtained the holotype. It seems best to restrict the
type locality to the place last mentioned.

Four specimens from southeastern Alberta recently reported by Moore
(1953:143) have been examined and seem best referred, among known
subspecies of _fasciatus_, to _P. f. olivaceogriseus_. They differ from
the latter in several minor cranial features and more drab back, sides
and lateral line. When adequate material is available they may prove to
be subspecifically different from _olivaceogriseus_. Moore referred
these specimens to _P. f. fasciatus_.

Specimens from extreme northwestern Nebraska, including the holotype,
are slightly darker than specimens from eastern Wyoming. A specimen from
Ft. Steele, Wyoming, shows approach to _P. f. litus_ in pale dorsal
coloration.
