the back, except that the annulations are broader; the under- 
side is suffused with yellowish, the tip is black. 
The skull is very long and narrow, and although undoubtedly 
that of a true Sevurus, in its restricted sense *, it shows con- 
siderable resemblance to the skull of a Funambulus. 
In size it is nearly equal to that of Funambulus Berdmoret, 
The nasals are intermediate, and while being flattened as in 
Sciurus, in length and proportions they resemble those of a 
Funambulus. The interorbital region and anterior end of the 
brain-case is bold, swollen, and rather broad in proportion to 
the general build of the skull. The postorbital processes are 
of moderate length and jut outwards more than in /. Berd- 
moret. ‘The zygomata are moderately straight and do not 
jut out, especially anteriorly, so much as is usually the case 
in Seturus. The brain-case, which reaches its maximum 
height at the level of the postorbital processes, falls away 
rapidly behind. ‘The teeth are of the ordinary Sciurine form 
and the auditory bulla rather small. 
Dimensions (from flesh):—Head and body 178 millim. ; 
tail 172; hind foot 40. 
Skull: greatest length 50; basal length 38; palatal length 
20°5; zygomatic breadth 27; interorbital breadth 15°5; 
length of nasals 15; breadth of nasals, ant. 6°7, post. 4.

The skull of this species is so distinct as to prevent any 
confusion with the existing species. Its nearest ally is most 
probably S. notatus, but its grey feet, the colour of the under- 
parts, and the patches of colour at the base of the limbs render 
its identification a matter of no difficulty.
