Lacomys. 375 
with a very slight rufous tint, and tipped with dark brown; below 
whitish with translucent dusky blue, —Stoliczka, quoted by Blanford. 
SizE.—From 7 inches to 9 inches. 
It is as yet doubtful whether this is not identical with the last. 
Mr. Blanford has separated it, and Dr. Giinther, agreeing with him, 
named this species LZ. Ladacensis ; but the skull characteristics of £. Cur. 
zonieé have not as yet been compared with this, and the separation has 
been made on external characters only. 
No. 421. LAGOMYS AURITUS. 
The Large-cared Pika. 
HasitTat.—Lukong, on the Pankong lake. 
DEScRIPTION.—General colour above smoky or wood brown; the 
head, shoulders and rump rather paler and more rufous; lower parts 
whitish, with the dark basal portion of the hair showing through ; fur 
very soft, moderately long; 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. (See Blanford’s ‘Sc. Res. Second 
Yarkand Mission,’ p. 75, plate vi. fig. 2.) 
Size.—About 8 inches. 
No. 422. LAGOMYS MACROTIS. 
This seems to be a doubtful species; it may probably prove to be 
the same as the last, the skulls being similar. Mr. Blanford remarks : 
“T am strongly disposed to suspect, indeed, that Z. awritus is the 
summer L. macrotis, the winter garb of the same species ; but there are 
one or two differences which require explanation. The feet appear 
larger in Z. macrotis, and the pads of the toes are black, whilst in Z. 
auritus they are pale coloured. In the former the long hair of the fore- 
head is lead black at the base, in the latter, pale grey; the feet and 
lower parts generally are white in Z. macrotis, buffy white in Z. auritus, 
but this may be seasonable.” 
No. 423. LAGOMYS GRISEUS. 
The Grey Pika. 
Hapitat.—Yarkand, Kuenlun range, south of Sunju pass. 
Description.—General colour dull grey (almost Chinchilla colour),
