Sp. Cu.—Among the smallest of the American rabbits ; considerably less than J. sylvaticus. Ears about as long as the 
head. Tail moderate. Hind feet longer then the head; very densely padded. Fur soft and full. 
Above, mixed black and brownish white; the black much developed posteriorly. Sides rather paler. Thighs and 
rump gray. ‘Tail above like the back. Back of the neck and fore legs rust color. Throat and sides of the neck with a 
tinge of pale rusty; along the edge of the abdomen this color concentrated almost into a lateral stripe ; paler than the 
back of the neck. Edge of the ear whitish; external and internal bands grayish brown. ‘The internal face rusty at base, 
then hoary, as on the exterior, for much of the surface. A narrow margin of black along the tip. Fur nowhere passing 
from the basal lead: color to dark brown without an intermediate bar of yellowish brown. 
Size considerably less than L. sylvaticus. Ears about as long as the head, pretty well furred. 
Feet moderate, very densely clothed with fur. Fur everywhere rather soft and full, especially 
ontherump. Tail moderate. 
General color on the back, mixed black and brownish white, the former rather predominat- 
ing. Sides lighter and with less of black, the transition, however, not abrupt. Rump and 
sides of thighs ash gray and black, different from the back. Upper part of the neck, clear 
pale rufous ; this color seen also on the outside surface of the fore legs. The under surface of 
the head white; the abdomen and inside of limbs white, with a tinge of yellowish rufous, 
especially about the thighs ; this tint concentrated along the edge of the abdomen almost into a 
band. The under part and sides of the neck are yellowish brown, decidedly different in tint 
from the sides of the body posteriorly. The anterior edge of hind legs is white tinged with 
rufous. Tail above like the back; beneath, white. The ears are whitish on their posterior 
edge. At the base of their dorsal surface they are rufous, shading into a very pale tint of the 
same, then ashy. A narrow border around the tip of the ear is black; the external bands 
mixed grayish and brown, like the lower part of the back. The inside of the ear is ashy white, 
brightest along the margin above ; the internal band is like the external. 
The fur is everywhere lead color at the base. On the anterior portion of the back, below the 
rufous portion, it shades into rufous, then brown, then light yellowish brown and with a slight 
tip of black ; proceeding towards the rump the rufous bar becomes more brown, then paler and 
paler, until the prevailing tint here is brownish white or gray. The subterminal brown band 
continues much the same until near the ramp, when it gradually almost disappears. The sub- 
terminal light bar is anteriorly very light yellowish brown, then becomes paler, until it is light 
gray posteriorly. The black ends to the hairs are much developed on the back. On the sides 
the colors are lighter to begin with, and become paler posteriorly to such an extent that, on the
