DESCRIPTION. 
Dental formula, incisors 2, canines *>3, grinders = = 22. 
Incisors exserted, strong, white ; upper ones rounded anteriorly, marked near their inner 
sides by an almost obsolete groove, and having even cutting edges. Lower ones longer, 
nearly linear, and rounded anteriorly. Of the upper grinders the anterior one is the smallest, 
the posterior one the widest, and the other three are nearly equal to each other in size. The 
crowns of the four posterior grinders are widest exteriorly, aud exhibit a duplicature of enamel, 
folded as it were from the outer side in such a manner, that the inner crest of each tooth 
forms a single rounded eminence, a very little higher than the rest of the crown. The outer 
crest or edge of the tooth, consists of three lower and more acute points. The smaller ante- 
rior grinder has an oval crown divided into two sloping surfaces by a transverse ridge. In 
each of the grinders of the lower jaw, the bounding ridge of enamel forms an anterior and a 
posterior pair of points, of which the anterior pair is considerably higher, and particularly the- 
inner point of that pair. ‘The inner point of the posterior pair of each tooth wears away in a 
cup-shaped form. The area of a section of one of the lower grinders is obliquely quadrangular ; 
whilst the areas of the four posterior upper ones are more nearly triangular. The lower molars 
increase slightly in size from the anterior to the posterior one, which is the largest. The frontal 
bone is flat and depressed between the orbits, and its nasal process rises, to form with the nasal 
bones an oblong arch. 
The body is thick and low, the head oblong, flat on the crown and between the eyes, with a 
slightly arched obtuse nose, covered with short hairs. Septum and margins of the nostrils 
naked. There isa duplicature or depression on the inside of the cheek, forming the rudi- 
ments of a pouch, and capable of containing a small bean. Whiskers shorter than the head, 
entirely black. There are some black sete on the eyebrows, a tuft containing about 
eight black hairs as strong as the whiskers, at the back part of each cheek, and a similar tuft 
between the posterior angles of the lower jaw. yes moderately large. Ears low, flat, and 
rounded, the anterior edge only doubling in, to form a helix ; they are well covered with 
short, adpressed, hoary hairs on the inside ; posteriorly, they are clothed with hairs similar to 
those on the adjoining part of the head. The ears are conspicuous enough, unless when the 
fur is in prime order, and consequently long. The upper surfaces of the head and feet are 
covered with a thick, smooth coat, of rather short hair, having a shining dark umber-brown. 
colour, which on the feet approaches to black. The end of the nose is, in some specimens, 
hoary ; in others brown. 
The fur on the back is of two kinds,—one, a fine wool or down, which, for half its length 
from the roots upwards, is of a blackish-gray colour, and, for the other half, is of a pure, 
shining, yellowish, or wood-brown. Intermixed with the down there are many longer hairs, 
which are brownish-black for two-thirds of their length, and are tipped with white. Some of 
them, however, are merely ringed with white, and are tipped with black, The resulting colour
