The geiicnil colour above is ratlicr jiale rufous, with a dusky wash caused 

 bj the tii^s of the longer hairs being black. There does not appear, in the 

 only skin I have examined, to be the grey rump of L. Pamirensis and 

 several other Central Asiatic species. The forehead and central portion 

 of the muzzle is j)ale rufescent grey, the hairs rufous ashy at the base, then 

 brown, and isabelline at the tips. The sides of the head are paler, but a 

 few black tips are found on the hairs of the cheeks. There is a pale ill- 

 defined band on each side of the muzzle, including the eye. Whiskers black 

 at the base, white towards the end ; some wholly white. Anterior portion 

 of the ears outside nearly the same colour as the forehead, hair soft, not so 

 dense and harsh as in L. JPamircnsis, posterior j^ortion of outer surface pale 

 rufous, extreme tip of ear black outside, the black running about a third 

 of the way down the posterior edge. Neck all round and breast pale rufous, 

 hairs ashy at the base and pale tipped, except on the nape. Fur of body 

 soft, on the hinder part of the back the hair is about 1\ inches long, and 

 consists of coarser piles mixed with fine woolly under fur. Throughout the 

 dorsal portion the hair is ashy at the base, then isabelline, followed by a 

 brown ring, the end being pale rufous, except in the longest hairs, which are 

 tipjDcd black. Tail sooty black above. Limbs externally pale rufous. 

 Underparts white. 



The skull of Lepus Biddulplii differs from that of L. Tihetanus in 

 the folloAving characters. The parietals are broader and flatter, the width 

 of the f rentals greater and they are somewhat more convex just behind the 

 post-orbital processes. The nasals are truncated behind, the angle formed 

 by the junction of the posterior and exterior margins being a right angle as in 

 L. Stoliczkaniis and L. Yarkandensis, differing in this respect from L. Tihe- 

 tanus, L. Pamirensis, and L. hypsihius. The hinder extremities of the pre- 

 maxillse are parallel with the hinder margin of the nasals, the jugal is 

 narrower vertically. The muzzle is less high and the whole skull flatter. 

 The palatal opening is smaller and differently formed behind. The open- 

 ing of the posterior nares is narrower. The lower jaw is much less high. 



The nearest apj^roach to the skull of L. Biddulphi, amongst the sj)ecies 

 of which specimens are available for comparison, is made by the hare which 

 inhabits the Karakash valley between Ladak and Yarkand. This species 

 much resembles L. pallipes of Hodgson from the portion of Tibet north 

 jf Nepal and Sikkim. In the skull of the Karakash hare, however, the 

 nasals extend backwards to some distance beyond the terminations of the 

 prcmaxillae, the zygomatic arch is broader and more convex beneath, the 

 postorbital processes are differently shaped and the whole skull larger.
