182 CLASS MAMMALIA. 



pale yellow, and scarcely any distinction of colour is appa- 

 rent above and beneath. 



The ears are acute, of moderate size, and covered with 

 delicate hairs, without any brush-like appendages. The 

 mustachios consist of numerous long, stiff, bristly hairs, 

 arising from the sides of the nose, and the upper lip, and 

 diverging from the head. A small tuft of separate, short, 

 stiff, black whiskers, parting backward, arises from the 

 cheeks about midway between the angle of the mouth and 

 the ears. 



The front teeth have a gall-stone-yellow tint, inclining to 

 orange, the upper lip is deeply divided. In its general 

 habits, as well as in the form of its head, and in the pro- 

 portions of the neck and limbs, the Sciurus Bicolor agrees 

 with the other large Indian Squirrels, and like these, it also 

 has a short, broad, obtuse nail on the thumb, which has 

 been aptly compared to that of several Monkeys. The thumb 

 itself is not lengthened or separated from the toes, but 

 consists of a thick fleshy tubercle supporting the nail. The 

 claws on the other toes of the fore feet, and all those on the 

 hind feet, are acute, and greatly compressed, as in other 

 species of this genus. 



The hairs of the upper parts are coarse. At the base, the 

 separate hairs are supplied with down, but they are ridged 

 and somewhat bristly at the extremity, and are not regu- 

 larly applied to the skin ; on the breast and abdomen, the 

 fur is softer, and the arms and paws are bordered with a 

 beautiful series of hairs, generally of a deep fulvous tint, 

 and extending laterally from the shoulder toward the ears. 

 From the outer margin of the fore-arm, near the foot, arise 

 several long, stiff, straggling bristles. 



We have availed ourselves thus largely of Dr. Horsfield's 

 observations on this species, not so much for the purpose 

 of describing it individually, as to illustrate the general his- 

 tory of the large Indian species. Dr. Horsfield's researches
