XIV. — Description of a new Bornean Tupaia. 

 By Oldfield Thomas. 



Tupaia gracilis^ sp. n. 



Intermediate in size between the smallest species of the 

 genus [T. javanica^ minor, &c.) and the middle-sized ones 

 {T. dorsalisj jncta, montana, and others). Build slender; 

 feet and tail long. 



General colour all over above, including the head, back, 

 outer sides of limbs, and upper surface of tail, clear finely 

 grizzled olive, nearly uniform throughout. Shoulder-streak 

 distinct, pure white. Under surface and inner sides of limbs 

 dirty whitish, the throat with a strong salmon-coloured suffu- 

 sion. Hind feet very narrow and elongated, recalling in their 

 proportions those of the very much larger T. ferruginea 

 longipes. Tail very long, fairly bushy, markedly distichous j 

 its upper surface coloured like the body, although ratlier 

 darker, its lower olive along the line of the vertebra?, then 

 with a broad yellowish band on each side, outside which the 

 hairs are finely ringed with black and yellowish. 



Skull short and broad, with a particularly short and stumpy 

 muzzle (see measurements). 



Dimensions of the type (an adult male in skin) : — 



Head and body 1G5 millim. ; tail 175; hind foot, without 

 claws, 38. 



Skull: greatest length, occiput to gnathion, 39'4; greatest 

 breadth 21; nasals, length 12, breadth 5*4; interorbital 

 breadth 12; orbit to gnathion 16*2 ; palate, breadth outside 

 ^Ei^ 12'8, inside ?^ 7"3 ; length of upper tooth-scries 19; 

 length of lower jaw 25"5 ; combined lengths of three lower 

 molars 7*6. 



A second specimen, also a male, preserved in spirit, 

 has a trunk-length of 138 millim., with its tail IGl 

 millim. and its hind loot 41*2 millim. in length; but the 

 differences between these measurements and those of the skin
