MAMMALIA. 



75 



Pur very soft, moderately long, about 0"9 inch long on the middle of the back, without any 

 scattered longer hairs, black and glossy (leaden black) at the base on the upper parts, some- 

 what more slaty on the sides and below, distal portion of the dorsal hairs whitish, tips dark- 

 brown ; the same on the sides ; on the abdomen the tips of the hair are white ; on the head 

 the basal portion of the hair is light slaty-grey, the tips rufous. Ears large, round, clothed 

 rather thinly inside near the margin with whitish-brown hairs, and outside with much longer 

 hairs of the same colour. Whiskers fine and long, the upper dark-brown, the lower white. 

 Feet whitish. 



The skin measures about 8 inches in length, the skeleton 7 (the living animal would 

 be rather more) ; the ears in the dried skin an inch in length or rather more, and the same 

 in breadth ; tarsus to end of claws 1*2 ; carpus to end of claws 07. 



In the skull the anterior and posterior portions of the anterior palatine foramen are 

 united, without any tendency to a constriction between them. The nasal bones are much 

 narrower than in L. roylei, and the sincipital portion is more convex ; otherwise there is 

 much resemblance between the two.

This species differs from L. roylei by its much larger ears and by its colour, which is 

 lighter. It probably is found in other parts of Ladak. 1 Skins obtained at Gilgit and in 

 the Kishengunga valley by Captain Biddulph, 2 however, appear to be intermediate in 

 characters between L. roylei and L. auritus.

There is a single specimen, without a label, of a Lagomys with the fur in poor condition, 

 in the collections made by Dr. Stoliczka. It has evidently been shot when shedding its long

 near Dras, Kharbu, Leh and Chagra, are not forthcoming.
