This species approaches L. tolai, Pallas, but is much smaller with proportionately longer 

 ears It appears to be the common species of the Kashghar and Yarkand plains, and may 

 very possibly be the hare noticed by 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 

 back ; terminal portion of ears black outside the edge ; breast light rufous ; lower parts, as usual, 

 white. Fur 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 back, but only to the scattered longer hairs. Length of ordinary hairs on the middle of 

 the back 1 to 1| 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 ruf escent isabelline, the 

 hairs being slaty- grey at the base. Face 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 band near the posterior margin, which is brown. Fore-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.
