This species approaches L. tolai, Pallas, hut is much smaller with proportionately longer 
ears. It appears to he the common species of the Kashghar and Yarkand plains, and may 
very possibly he the hare noticed hy Prejevalski near Lake Lob.

General colour very pale sandy-brown, almost isabelline on the back and sides; rump 
greyish white ; tail black above; face and anterior portion of the ears the same colour as the 
hack; terminal portion of ears black outside the edge; breast light rufous; lower parts, as usual, 
white. Pur fine, close and soft, consisting at the base of fine woolly fibres mixed with coarser 
hairs, the former slaty-grey for about half an inch, then pale-rufous passing into dusky- 
brown, the tips being sandy. Throughout the fur coarser and longer piles are scattered; these 
are white near the base on the back, showing conspicuously amongst the grey under-fur, and 
black at the ends. The basal portion of the fur is darker on the rump, sides, and shoulders, 
than on the middle of the back. There are no black or dusky tips to the fur in general on 
the hack, but only to the scattered longer hairs. Length of ordinary hairs on the middle of 
the hack 1 to 1J inches, longer piles to f inch more. On the rump, as usual, the hair is 
longer. The nape, sides of the neck and breast are pale rufous, or rufescent isabelline, the 
hairs being slaty-grey at the base. Pace and sides of head pale sandy-brown, nearly the 
same as the back, with longer black piles scattered throughout the fur; hairs slaty at the 
base, then brown, tips sandy; a very distinct white line from the upper lip to behind the 
eye, which it includes; chin and upper part of throat pure white. Ears sandy brown on the 
anterior outer surface, nearly the same colour as the face, anterior margin white, posterior 
outer surface creamy-white, becoming rufous near the base; outer margin at the apex and 
for a varying distance down the hinder margin black or blackish. 1 Hair on inside buffy- 
white, except the hand near the posterior margin, which is brown. Pore-legs in front and 
hind-legs outside with a light brownish tinge ; pads much darker. Hairs of the tail white 
throughout their length below and on the sides, black throughout above. Both animals were 
shot on May 1st. They do not appear to have lost their winter coats. 
1 This probably varies with the season; it is more distinct in one specimen than in the other.
