quintam partem totius longitudinis subcequante , pills fulvescenti-albidis setosis instructd; 
dente molario maxillari ultimo angusto, intus angulis duobus fortioribus antice, nullis 
postiee, extus quatuor parvulis, duobus antice , ceteris postice, spatio interveniente, munito.

1, Nubra valley, N. of Ladak; 2. Aktagh, on the upper waters of the Yarkand river. 
General colour bright ferruginous, brown above, pure white beneath. Fur soft, rather 
woolly, 0’5 to 06 inch long on the middle of the back, the basal portion throughout both 
head and body being dark leaden-grey: this is the case on the back for about three quarters 
of the length of the hairs; the remaining quarter is rufous-white, tipped with darker rufous, 
whilst numerous rather longer hairs are dark rufous-brown at the ends. Luther a sharp line 
divides the rufous of the back from the white belly. Upper part of the head the same colour 
as the back. Upper whiskers dark-brown; lower, including the longest, white. Ears small, 
rounded, hairy, completely concealed by the fur, with rather short bright rufous hair near 
the margin inside, and covered outside with longer and paler hair. Feet small, the thumb 
of the fore-foot quite rudimentary and clawless; remaining clav r s long, compressed, sharply 
pointed, but much concealed by the long white hairs, which cover the upper part of the 
foot; soles naked ; tarsus hairy below, a few hairs between the pads of the toes. Tail short, 
apparently about a quarter the length of the body and head together, covered with stiff 
fulvescent white hair, which extends about half an inch beyond the end. The dimensions 
are taken from dried skins, and are consequently only approximations; length of head and 
body 4 inches; tail with terminal hairs T|, without hairs 1; tarsus and hind-foot to end of 
claws O'7 ; ear from orifice 0'35; breadth the same.

The nasal bones have a slightly concave outer margin, and their posterior termination is 
rounded. The incisors are deep yellow in front; 
the upper pair having 
a very shallow 
groove down the centre. The anterior molar in the upper jaw consists of five prismatic lobes, 
and has three salient angles on each side; the second consists of four prisms, and has three 
angles outside, two inside; the third is peculiarly formed: it has two strong salient angles 
on the inside, and two very weak outside in the anterior portion, which is followed by 
an elongate process having two 1 slight projecting angles on the outside only, so that altogether 
this tooth has two strong salient angles inside, and four—all much weaker—outside; the front 
inner pair separated from the hinder pair by a deep groove. 
In the lower jaw the anterior molar is much the largest, and the hinder small; the first 
has five projections on each side,—the anterior pair very small and blunt; the second has three 
1 The hindmost is not shewn on the figure, PL X b, fig. 2, as it is scarcely seen on the crown of the tooth; ■ it is at the inner 
hinder extremity, or at the left hand lower termination of the figure, and is blunter than the angle just in front of it.
