description. 
This interesting species is similar to others composing a certain group 
of hares found in America, characterized by being large, and having very 
long ears, and long and slender legs and bodies, the whole form indicating 
capacity for long leaps and rapid locomotion. In all these characteristics, 
Lepus Callotis approaches nearest to Townsend’s hare, {Lepus Town- 
sendii,) which may be considered the type of this group. 
COLOUR. 
The whole of the upper surface, fawn colour, tipped with black ; hairs 
on the back, silvery gray for one-third of their length, then pale fawn, 
then black, then fawn, tipped with black. Back of the neck, brownish 
black, slightly tipped with fawn. A number of hairs of unusual length, 
Itwo and one-fourth inches,) and delicately interspersed along the sides ; 
in the greatest abundance along the shoulders. These hairs are black 
from the base for two-thirds of their length, the remainder pale fawn ;
