S. jhilaysoni Jinlaijsoni has been recorded b}^ Anderson from the

 ivory yellow, top of head slightly deeper yellow ; the sides of head, fore 

 and hind limbs greyer owing to decrease in the yellow element, pro-

liemarks. This squirrel is subject to a certain amount of valua-

 region is considerably darker and greyer than as given above. In some 

 animals there is no tawny wash on axillae and groin, in others these 

 areas are pale chesnut and the lower abdomen is also suffused with this 

 colour. 



One example has the tail ivory white throughout as in S. jinlai/soni 

 poriiis from the neighbouring island, two or three have the tip only 

 darkened, while in a number of the specimens the tail is throughout
