Upper Jaw. — Front teeth ; one on each side, oblique, closely applied to the 

 canine teeth at the base, which has a slight marginal enlargement ; point conical and 

 simple, with a strong inclination inward. Canine teeth of moderate size, erect, 

 with a small, compressed, vertical heel at the base, by which they meet the first 

 grinder. Four carnivorous teeth (carnassieres) on each side ; the first with a conical 

 projecting point, and an interior dilation at the base ; the second and third very 

 large, compound, and having the usual form of the large grinders in this Family ; 

 the fourth small, and greatly compressed. Lower Jaw. — Front teeth six, nearly 

 equal in length, less strongly emarginate than in other species. Canine teeth very 

 slightly curved, and tending outward, base having a marginal heel interiorly. First 

 grinder very minute, regularly disposed in the series, compressed at the base, with a 

 short, acute, conical point ; second grinder having a somewhat compressed point, pro- 

 jecting sUghtly beyond the other teeth, and an internal heel at the base, which is 

 closely applied to the third grinder ; this, as well as the fourth, is very large ; the 

 fifth is, as usual, somewhat compressed posteriorly. 



The head is of moderate length, broad between the ears, and ver'y gTaduaUy 

 contracted in dimensions towards the nose ; it is nearly even above, compressed at 

 the sides, and its vertical dimensions are proportionally great. The muzzle is broad, 

 and abruptly terminated. The nose is shghtly emarginate, and the apertures of the 

 nares are directed downwards. The eyes are distinct, and more prominent than is 

 usual in this genus. One of our specimens has an indication of the sebiferous glands, 

 in a semilunar rib, extending across the face before the eyes. The angle of the 

 mouth (mundwinkel) is proportionally small, and terminates under the eyes ; while 

 in many species of this genus it extends backward to the region of the ears. The lips 

 are not thickened or rugose, but bordered, and nearly concealed by dehcate hairs. The 

 ears are somewhat shorter than the head; the auricle is oblong, erect, rounded, 

 obtuse, naked, and slightly indented posteriorly ; it is continued into a narrow border.
