I therefore give a description of the points in which the differences 

 are most noticeable. The naiiie of trilineatus must be used as 

 although it only appears as a nomen nudum in 1850* and in 

 185 If Blyth mentions it as a synonym oi Sc. delesserti, Kelaart 

 published a description of the Ceylon squirrel under this name in 

 1852, though he did not separate it from the S. Indian species and 

 gave Waterhouse the credit of describing it, including Sc delesserti 

 and sublineatus as synonyms. 



It is a small Funamhulus similar to suhlinecdus in general appear- 

 ance, but differing from that species in being larger throughout, and 

 darker in colour, having more brown and less of the olive shading 

 which is pronounced on the mainland species, this browner tinge being 

 especially noticeable on the flanks ; the tail much more bushy, the 

 hairs decidedly longer and more coarsely speckled ; stripes down 

 the back wider and less distinct. The skull measurements larger. 

 Fur soft and very dense. 



General colour dark brown finely speckled with yellow, three 

 slightly paler longitudinal stripes with a darker brown, less speckled, 

 fur between them, the stripes become indistinct on the shoulders 

 and rump. Underside pale tawny ; flanks ruddy brown. The hair 

 on the tail is black at the base, followed by a narrow band of tawny, 

 then a wide black band tipped with pale yellow, while in stdMneatus 

 the hairs are much shorter and evenly speckled brown and yellow 

 throughout. 



Dimensions (measured in the flesh). — Head and bod}^ 125 (120) 

 mm.; tail 122 fll7) ; hindfoot 31 (29) ; ear 13 (13) . 



SJiull. — Greatest length 37' 7 (35) mm.; condylo-incisive length 

 32-5(30); basilar length 27-6(25-3?); tooth row (upper molar series) 

 7 (6-6); diastema 8-4(7); nasals 11 f9-9); zygomatic breadth 20-8 

 (19-2). 



(The figures in brackets refer to a specimen of suhlineatus from 

 Coorg.) 



The specimen described is a young male, collected hj Major E. 

 W. Mayor at Kottawa, S. P. Oevlon, on April 11th, 1913. Original 

 No. 13. 



Five specimens from Ceylon and 19 from Southern India are avail- 

 able for comparison and the distinguishing characters are constant 

 throughout the two series. 



Ji. — SCIURUS ATRODORSALIS SHANICUS, Subsp. n. 



North Shan States Blach-backed Squirrel. 



A squirrel .similar to Sciwnis atrodorsalis but without the red 

 underside and practically without the black patch on the back.
