1, 2, Jigda, Altum Avtush district, N.-E. of Kashghar. 



This species is very close to L. pamirensls, but appears to be distinguished by its much 

 longer ears, by wanting the distinct white cheek bands, and by having black tips to the dorsal 

 fur, producing a blackish wash on the back. The fur is rather softer, and the colouration 

 of the underfur darker. 



The general colour above is light sandy-brown, much mixed with black on the back ; the 

 rump very little paler ; tail rather long, black above ; face and anterior portion of ears the 

 same colour as the back ; terminal portion of ears black outside ; nape and breast light rufous, 

 lower parts white. Fur soft and long, consisting, as in the last species, of two kinds, the one 

 woolly and fine at the base, the other longer, coarser and straight throughout ; throughout the 

 upper parts the fur is ashy at the base for about three-quarters of an inch (the colour being 

 much darker and slaty on the shoulders, sides and rump, paler in the middle of the back), then 

 brown for half an inch, light at first, becoming darker away from the body, the portion near 

 the end is sandy-brown, and the tip itself in many hairs black on the back only. The longer 

 scattered hairs are white at the base, and conspicuous amongst the finer grey woolly fur, 

 and have the distal portion black. Length of ordinary fur on the back 1-| inches, the longer 

 piles half an inch more. Nape, back and sides of neck and breast pale rufous ; the hairs dark 

 slaty at the base, but this colour on the nape is only perceptible quite close to the skin. 

 Face sandy-brown, fur slaty at base, then chocolate-brown ; the tips very pale sandy ; longer 

 black piles are scattered throughout. A faint line from the nose to the eye, and hah' around 

 the eye pale, but there is no distinct white band. Upper and shorter whiskers black, lower 

 long whiskers white, black near the base. Ears in front sandy brown like the face ; hair on 

 the anterior edge white ; posterior portion of outer surface pale rufous or buffy- white, near 

 the tip black, this colour running as a narrow line for some distance down the posterior 

 margin. Hah 1 inside the ear mostly white, buff towards the edge, darker band inside the 

 posterior edge dusky brown, not much developed. Hind-legs on outside, and fore-legs in 

 front, pale sandy rufous ; pads darker. Hair of tail white throughout below and on the sides, 

 black throughout above. 



The following are the dimensions of the skins : length, nose to rump, 17"5 ; tail (verte- 

 brae), 3 ; hair at end of tail, 2 ; length of ears from head, 52 ; length of ears from orifice, 

 4s 25 ; breadth of ears laid flat, 2*5 ; tarsus to end of claws, 4*9. 



The skull (PI. Va, fig. 2) differs much both from that of L. yarkandensis and that of L. 

 pamirensis, the nasals being much more abruptly truncated behind than in either, and the 

 parietal region or sinciput flatter. The size is about the same as that of the latter. The 

 following are the dimensions, the length being only approximate, as the occipital portion in 

 both specimens is imperfect.
