(8) Petaurista caniceps, Gray. 



1842. Pteromys caniceps. Gray. A. M- N. H., X. p. 262. 



1844. Pteromys senex, Hodg., J. A. S. B., XIII, p. 68. 



Synonymy.— Pteromys senex was described by Hodgson from 

 Nepal before 1842 but owing to a delay in preparing the plates 

 was not published until 1844. In 1842 Gray described a Sikkim 

 specimen as caniceps. 



Description. — Size as in inornatus and birrelli. In general 

 colouring it closely resembles birrelli, both above and below, but 

 the whole head is drab grey and the hands and feet are ochraceous 

 rufous and not black or partially black as in inornatus and 

 birrelli. 



Size. — The following dimensions were recorded by Hodgson : — 

 Head and body, 350 ; tail, 400 ; hindfoot, 68. Skull, greatest 

 length, 66 ; basilar length, 52 ; greatest breadth, 43 ; molars, 15. 



Remarks. — This seems to be the form of the middle Himalayas.
