the end, the tips being black. As usual the longer hairs are most abundant 

 near the middle of the back, less so on the sides. Forehead rufous mixed 

 with black, the sides of the head are dark ferruginous above, paler below, 

 shading off gradually into the colour of the face and throat. Ears rounded, 

 covered thinly inside and out with short hairs ; a little patch of silky white 

 hair behind each ear is concealed by the ear conch when the ears are laid 

 back.* Whiskers black. The hairs of the lower parts are dark grey at the 

 base, Avhite at the ends, there is a tinge of rufous on the fore neck and 

 throat in some specimens. Fore limbs yellowish olive outside, like the 

 sides, whitish inside, hind limbs also whitish within, but more rufous out- 

 side. Tail clad above with black hairs, having a white ring near, but not 

 at their base, and white tips, so as to produce a very beautiful hoary appear- 

 ance, lower surface of the tail chesnut, the longer hairs on the sides with 

 black and white tips 



The following dimensions in inches were taken by Mr. Davison on 

 fresh specimens :

Length from nose to insertion of tail, 7"3 8*2 8'1

The skull (Plate VII) differs considerably from those of S. lokrioides, 

 S. atridorsalis, S. caniceps^ S. pTiayrei, S. hlanfordi and all other allied 

 species with which I have been able to compare it, in the narrow and 

 singularly elongate nasal portion, in which character the present species 

 shews an approach to BheitJirosciurus of Gray. 



The following are the dimensions of the skull of the present species,, 

 compared with those of some of the other Himalayan and Burmese forms.
