ightly lighter than head and rump;
lateral stripes white; head and rump 'pale smoke gray';
postauricular patch grayish white, a narrow margin extending
up posterior border of ear; anterior portion of ear 'fuscous
black' mixed with 'verona brown' at base and bordered by
light gray; ocular stripe black grading into 'verona brown'
in front of ear; submalar stripe nearly obsolete, 'sayal
brown'; sides of body grayish washed with 'verona brown';
feet grayish very faintly washed with 'pinkish buff'; dorsal
surface of tail black overlaid with 'tilleul buff'; ventral
surface of tail 'cinnamon buff' narrowly bordered by black
then by 'tilleul buff'; ventral surface of body white." (Burt
1931:299.) Skull similar to that of _E. u. inyoensis_ but
differing as indicated below.

_Comparisons._--From _E. u. inyoensis_, the subspecies to the
north, _E. u. nevadensis_ differs in: Paler and grayer
throughout; tawny areas restricted; gray areas clearer and
less suffused; dark facial markings narrower and less
distinct; ventral surface of tail distinctly paler; feet
lighter, clearer gray; nasals extend farther posteriorly with
respect to premaxillae (Burt _loc. cit._).

From _E. u. adsitus_, the subspecies to the northeast, _E. u.
nevadensis_ differs in: Narrower dorsal stripes and facial
markings; paler coloration of head, rump, sides, feet, and
ventral surface of tail (Burt _op. cit._: 299-300).

_Remarks._--The differences between _E. umbrinus nevadensis_ and _E.
palmeri_, as shown by Burt (_op. cit._) and Hall (1946), are such that
one might expect _E. palmeri_ to be a subspecies of _E. umbrinus_.
However, having only the structure of the baculum as evidence
additional to that summarized by Hall (_op. cit._), I follow him in
according _E. palmeri_ specific status.

_Specimens examined._--None.
