This species, which is of small size, is represented in the India Museum, London, 

 by the type. It is distinguished from aU other flying squirrels by the series of 

 bristles or vibrissse disposed on the cheeks in a radiated manner. The head is short, 

 ovate, laterally compressed and attenuated to a short obtuse muzzle which projects 

 beyond the lower jaw. The lobe of the ear at its base has a thick tuft of silky 

 hair of a white colour. The tail is distichous, and equals in length nearly two-thirds 

 of the body of the animal. 



The general colour is grey above and white beneath, the upper surface of the 

 head being purely grey. On the neck, the back, and the tail, the colour has a 

 brownish tint, incHning to tawny. The anterior and middle parts of the membrane 

 are sooty-brown diversified with greyish hairs.

i I have not been able to reconcile any of the above small flying squirrels with the S. sagitta, Linn., but I here 

 give the principal references to S. sagitta which was described from a Javan specimen —
