total length 914; head and body 495 ; tail vertebrae 419; hind foot 

 76 (71). The fur is much paler in color than specimens from Trong, 

 Lower Siam, and the stripes on the back show a strong tendency to 

 break up into rows of spots. Skull of same size as in Trong speci- 

 mens, but audital bullae slightly less inflated, and paroccipital proc- 

 esses shorter and broader. Teeth too much worn to show any char- 

 acters.

TUPAIA BUNO^ sp. nov. 



Type. — Adult female (skin and skull). No. 101640 United States 

 National Museum. From Pulo Bunoa, Tambelan Islands. Collected 

 August 5, 1S99. 



Characters. — Externally similar to Tupaia tana but fulvous of un- 

 derparts, and especially that of under side of tail paler. Skull with 

 broader antorbital region and larger, more inflated audital bullae than 

 in T. tana. 



Color. — Back behind shoulders glossy seal-brown, the shorter hairs 

 narrowly ringed with orange-rufous subterminally and thus producing 

 an inconspicuous grizzle better defined in some lights than in others. 

 On sides and outer surface of legs the brown gradually gives way to 

 the orange rufous, but nowhere entirely disappears. Head, nape, and 

 shoulders a fine grizzle of sepia and yellowish white, the grizzled area 

 narrowing posteriorly and extending back in median line slightly be- 

 hind shoulders. It is traversed by a median seal-brown line about 3 

 mm. in width, extending nape to dark area of back. Immediately over 

 each shoulder is a faintly defined oblique pale stripe. Entire ventral 

 surface of body and inner side of legs ochraceous, fading to ochra- 

 ceous-buff on throat and chin and becoming somewhat darker and 

 more dull (nearly clay color) on inner side of hind legs. Tail ferru- 

 ginous throughout, the dorsal surface strongly washed with seal brown, 

 especially near base. Feet, ears, and muzzle dull brown. The fur of 

 the body is everywhere slate gray at base, less noticeably so below than 

 above. 



Skull. — The skull of Tupaia bunoce closely resembles that of T. 

 tafza from Linga Island but is slightly larger and has a distinctly less
