180 CLASS MAMMALIA. 



ternal sides of the limbs are white ; the paws are yellowish 

 brown. 



Dr. Horsfield says, that the external covering of this spe- 

 cies is subject to greater variations than any of the Indian 

 Squirrels, some being pale yellow, and others deep brown. 

 In several the colour is uniform, in others it is distributed 

 in irregular patches of different shades ; but the separate 

 hairs are not variegated or banded, as in many other spe- 

 cies. The darker specimens, he states, have some resem- 

 blance to the S. Bicolor ; but the examination of numerous 

 specimens has convinced him, that these two species are 

 decidedly distinct. The tint in the Bicolor is of the deepest 

 black, and the tail in the adult specimens, is often gray or 

 yellowish, and it has a different form and termination. 



The tail, therefore, seems a much more correct test of 

 this species than its general colour. The specimen brought 

 by M. Leschenault de Latour from Java, and deposited in 

 the French Museum, (the same we have engraved,) is re- 

 markable, and would be with aptness named the White- 

 headed Squirrel, and, in fact, it was at first so named by the 

 French ; but the species being subject to vary, so far as to 

 lose this distinctive character, it becomes necessary to dis- 

 tinguish it by another name. It is the Jeralang of the 

 Javanese. 



The disposition in the species of this genus to vary, al- 

 ready alluded to, is equally apparent in the common species 

 of our own part of the world ; in those, particularly, of a 

 gray or dark colour in America, and in the larger species of 

 Asia and the Eastern Isles. On the last of these, including 

 the Jeralang, or Leschenault's Squirrel, we have lately 

 had some very valuable observations from the pen of Dr. 

 Horslield. 



The Sciurus Bicolor is found on the continent of India, 

 and in Cochin China, almost entirely black above, and 

 golden yellow underneath. It measures about three feet
