SCIURUS HIPPURUS. 



/ 



Sciiinis hippiiriis^ Is. Geoff. Etud. Zool. i. 1832, n. 6. 

 tab. 6 ; 



This well ma-ked species approaches S. crvthrcrus in size. 

 The lower parts and inside of the limbs are deep ruddy ferru- 

 ginous; the head, sides of neck, shoulder, outside of fore limb, 

 thigh, and outside of hind limb, being minutely speckled with 

 white on a blackish ground ; feet black, the rest of the upper 

 parts of the body with the base of the tail yellowish-rufous, 

 punctulated with yellow and black ; tail bushy and black ; 

 whiskers black. The specimens in the British Museum ob- 

 tained by me from the Baram district are slightly different in 

 the deepness of the colour, being a rich uniform chestnut on 

 the back. This squirrel is usually seen on the ground, but takes 

 refuge in the trees when frightened. It is common all through 

 the low country in Sarawak, and does not ascend the moun- 

 tains above 3000-ft.

SCIURUS PRYERI. 



Sciunis prvcri, Thomas. Ann. Mag. Nat Hist. Sept.

This squirrel strongly resembles Sciiirns hippiirus, Geoff., 

 in general appearance, although slightly smaller and more 

 slenderly built, and agreeing precisely with that animal in the 

 grizzled yellow colour of the back and the grey of the head 

 and fore quarters, and their relative distributions on the 

 anterior part of the hotly, but distinguished, firstly, by its 

 wholly white instead of rich rufous belly ; secondly, by its hips 

 being yellowish like the back, instead of grey like the head ; 

 thirdly, by its feet being grizzled grey instead of black ; and 

 finallv, by its tail-hairs being broadly and conspicuously an- 

 nulated with black and white, with white tips instead of being 

 wholly black. Premolars f ; incisors orange yellow, not 

 darker above than below. 



Dimensions of the type (an adult male in skin) : — Head 

 and body 260 millim. ; tail 250 ; hind foot 54. Hab. [of the 

 type (B. M. No. 92. 7. iq. i),] Sapugaia River. 



As yet this species has not been prucured in the Baram 

 district.
