the hack, except that tlie aimuhitions are broader; the umler- 

 side is suflTiiscd with yellowish, the tip is black. 



The skull is very long and narrow, and although undoubtedly 

 that ot' a true ASciurus, in its restricted Sfiist- *, it shows con- 

 siderable resemblance to the skull of a Funambuhts. 



In size it is nearly equal to that of Funnmhulus Berdniorei. 

 The nasals are intermediate, and while being flattened as in 

 Sciurus, in length and proportions they resemble those of a 

 Funambuhts. The interorbital region and anterior end of (he 

 brain-case is bold, swollen, and rather broad in |)ro|)ortion to 

 the general build of the skull. The |)Ostorbital processes are 

 of moderate length and jut outwards more than in F. Btrd- 

 tnorei. The zygomata are moderately straight and do not 

 jut out, especially anteriorly, so much as is usually the case 

 in Sci'urus. The brain-ease, which reaches its maxiniuni 

 height at the level of the postorbital processes, falls away 

 rapidly behind. The teeth are of the ordinary iSciurine form 

 and the auditory bullai 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. notdtns, but its grey feet, the colour of the under- 

 parts, and the patches of colour at the base of tiie limbs render 

 its identification a matter of no difficulty.
