XIV.—Description of a new Bornean Tupaia. 
By OLDF1ELD THOMAS. 
Tupata gracilis, sp. n. 
Intermediate in size between the smallest species of the 
genus (7. javanica, minor, &c.) and the middle-sized ones © 
(7. dorsalis, picta, 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 7. ferruginea 
longipes. Tail very long, fairly bushy, markedly distichous ; 
its upper surface coloured like the body, although rather 
darker, its lower olive along the line of the vertebre, 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 165 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 162 ; palate, breadth outside 
m2 12°8, inside ™? 7:3; length of upper tooth-series 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 161 
millim. and its hind foot 41°2 millim. in length ; but the 
differences between these measurements and those of the skin
