SECOND YARKAND MISSION. 
and the points are pale buff, almost cream colour, but some of the hairs have blackish tips, which 
are in some specimens sufficiently numerous to produce a distinctly dark wash. The length 
of the fur on the middle of the back is about 1\ inches. On the sides and rump the hair is 
darker grey at the base, and the dusky ring near the tip is wanting. The hairs on the nape 
are pale rufous throughout, on the breast pale rufous to almost white, with the basal portion 
ashy. Hair of the face rather long, ashy at the base, then brown, becoming darker near the 
tip, which is generally very pale; some hairs, however, have black tips. Round the eye the 
fur is paler. Whiskers very few and inconspicuous, the upper black, the lower brown or 
white. Anterior external surface of ears the same colour as the face, posterior portion light 
isabelline or whitish. The apex in some is dusky, but in two specimens out of the four this 
is scarcely perceptible, and it is not black in any. Long hairs on anterior edge of ear white, 
those inside the ear of the same colour, but becoming buff towards the margin; the dark 
band near the posterior edge very faint. Eore-legs very pale brown in front; hind-legs still 
paler brown outside; pads rather darker, but variable as usual. Tail white below and at the 
sides, with a broad dark brown band above, the hairs of which are dusky grey at the base. 
One striking peculiarity of this very pale coloured hare is the absence of any black 
patches and of all grey colouration throughout. All the specimens were shot in winter. The 
animal is very small, the following dimensions being from one of Dr. Stoliczka’s labels to a 
Yarkand skin:—

In the skin the length from nose to rump of this specimen is 18 inches; ears from head 
between the ears 4*3 ; width of ear laid flat 2*25; tarsus 4 to 4*25. In the skeleton the skull 
measures 3*2 inches, vertebrae of neck and body 115, tail, consisting of 12 vertebrae, 3*25. 
The following are the dimensions of a skull, (PI. TV a, fig. 2.) It is very small, though 
fully adult, with peculiar short nasals, which are somewhat irregularly truncated behind near 
their outer margins, but slope away from the posterior end of the suture, where the frontals 
project forward in a point; each nasal is convex in front, the suture occupying a depression. 
The breadth behind the postorbital processes is greater than in the allied species, and the 
supraorbital expansion of the processes is smaller than usual in the genus :—

1 This, I think, does not include the tail.
