pecies to the east,
_E. m. consobrinus_ differs in: Color darker; size smaller; skull
narrower and shorter; baculum shorter.

From _E. m. confinis_, the subspecies from the Big Horn Mountains,
_E. m. consobrinus_ differs in: Over-all tone of upper parts less
grayish; underside of tail lighter; skull narrower and shorter;
baculum shorter.

For comparisons with _E. m. minimus_ see the account of that
subspecies.

_Remarks._--Specimens of this subspecies from the area between the
Uinta Mountains and the mountains of the Wyoming and Wind River ranges,
are clearly intergrades between _E. m. consobrinus_ and _E. m. minimus_
and are here referred to _E. m. consobrinus_. These specimens are paler
than typical _E. m. consobrinus_ and considerably darker than _E. m.
minimus_. These intergrades came from an area where the habitat is
intermediate between that of _E. m. consobrinus_ and _E. m. minimus_
but more nearly like that of _E. m. consobrinus_.
