Sciurus Brookei, sp. n. 



Allied to and of the general colour of typical Singapore 

 Bpecimens of S. tenuis^ Horsf., but distinguished by its much 

 larger size and by its cheeks, anal region, and the proximal 

 inch of the tail beneath being bright rufous.

Sciurus Lowii, sp. n. 



Size and general colour above of S. tennis, Horsf., but 

 darker, sleeker, and more finely grizzled. Ears black-rim raed. 

 Whole of under surface and inner sides of limbs pure white or 

 yellowish white, without admixture of grey. Tail broadly 

 ringed with orange and black. Muzzle of skull markedly 

 longer and interorbital breadth less than in ^S*. tenuis ; incisors

The occurrence of a typical grey-bellied short-snouted 

 S. tenuis in Mr. Everett's Barau) collection proves that this 

 white-bellied form, of which the Museum possesses six speci- 

 mens, is really distinct from that animal, with whicii 1 had 

 hitherto provisionally left it. 



The difi'erence in proportion between the skulls of S. tenuis 

 and H. Loicii is readily siiown by the fact that in the former 

 the interorbital breadth is equal to the distance from the front
