lor, tipt with black. Hairs on the hack silvery- 
gray for one-third of their length, then pale fawn, 
then black, then fawn and tipt with black. Back 
of the neck brownish-black, slightly tipped with 
fawn. A number of hairs, of unusual length (2i 
inches) and delicacy, interspersed along the sides ; 
in greatest abundance along the shoulders ; these 
hairs are black from the base for two-thirds of their 
length, the remainder pale fawn. Sides, and under 
parts of the neck, dingy pale fawn, gradually be- 
coming white on the chest. Haunches, legs, and 
tinder surface, white ; the white hairs on the rump 
annulated with black, and near the root of the tail, 
almost entirely black. The hairs on the under sur- 
face of the feet red. Ears, posteriorly, for two- 
thirds, black at the roots, gradually blending into 
fawn, and on the interior third mixed with black 
hairs, edged at the tip with black, the remainder of 
the edge fawn ; the outer margin of the posterior 
surface to its apex, pure white. Inner surface of 
the ears nearly naked, except at the outer edge, 
where they are clothed with short, grizzled-brown 
hairs. Whiskers white and black, the former 
predominating. Chin and throat white. The 
marginal line of demarkation, between the color 
of the hack and that of the under surface, is 
somewhat abrupt across the upper portion of the 
thighs, and very distinctly marked, so as to give 
the animal the appearance of a commencement of 
a change of color from fawn to white.
