ke Gray mixed
with Saccardo's Umber; dorsal surface of tail black mixed with
Buckhorn Brown; ventral surface of tail Sayal Brown, with Fuscous
Black around margin and white or Light Buff around outermost edge;
antipalmar and antiplantar surfaces of feet Warm Buff; underparts
creamy white with dark underfur. _Skull_: Large; zygomata strong
and arched; braincase well inflated. _Baculum_: Broad at base;
shaft tapers sharply to tip.

_Comparisons._--From _E. u. montanus_, the subspecies from the
Medicine Bow Range of south-central Wyoming, _E. u. fremonti_
differs in: Over-all tone of upper parts darker; underside of tail
darker; feet darker; sides darker.

For comparisons with _E. u. umbrinus_ see the account of that
subspecies.

_Remarks._--This subspecies normally occurs in the forest as do the
other subspecies of _E. umbrinus_ in Wyoming. A single specimen taken
at 12 mi. N and 3 mi. W Shoshoni, Fremont County, is the exception
which probably indicates that _E. umbrinus_ does occur outside of its
normal habitat and that gene-flow exists between the subspecies of this
species.
