MAMMALIA.

No specimen of N.' scnllyi was obtained by Dr. Stoliczka. The type, a dried skin of a 

 male, now in the Indian Museum, was collected by Dr. Scully on June 11th, 1875, at Sanju, 

 close to the base of the Kuenlun, south-east of Ytirkand.

Colour above hair brown, below whitish, the colours passing into each other ; fur soft 

 and rather long, about 035 inch on the middle of the back ; all, except the tips, both above 

 and below, dark slaty-grey, the terminal portions of the shorter hairs on the back being 

 light-brown, that of the longer hairs, which are about 045 inch long and very numerous, 

 dark-brown. Face much the same colour as the back, also with long blackish hairs scattered 

 over it, the upper whiskers black ; the lower, some of which are longer than the head, white. 

 Ears oval, clad with rather scattered light rufous-brown hairs near the margin inside, and 

 on the anterior portion of the outer surface, on the posterior outer surface the short mar- 

 ginal hairs are whitish, the hairs on the portion of the outer surface near the head are long 

 and pale coloured. Feet thinly clad with short light-brown hairs, tail with short bristly 

 hairs, which are dusky-brown above, whitish below. The colour of the type has become 

 paler and more rufous since the above description was written in 1875. 



The tail, which is fine and tapers gradually and regularly from the base to the tip, ex- 

 ceeds the head and body in length. The hind feet are rather long and narrow, the tubercles 

 beneath them are thus distributed : the distal pair, as usual, close together at the base of the 

 three middle toes, the outer tubercle of the next pair considerably farther from the heel than 

 the inner, and the outer tubercle of the proximal pair nearer to the inner of the second pair 

 than to the proximal inner tubercle. The fourth toe is distinctly shorter than the second. 

 Beneath the fore-foot the two proximal tubercles almost form an oblique line with the hallux, 

 but are rather nearer the wrist ; the second digit is shorter than the fourth. All the claws 

 are pale coloured and all compressed except that of the rudimentary hallux. 



The following dimensions, being taken from a specimen in spirit, are rather less than 

 those of the animal when alive : —

Do. of ear from orifice .... 

 Breadth of do. laid flat ....

The skull differs from those of M. musculus, M. syloaticus, M. bactrianus, and most 

 other species in having the malar bone distinctly concave on its outer surface, so that the
