A COLLECTION OF MAMMALS FROM SIAM. 13 



comes an emarglnatioii follower! for about 5 mm. by another convexity 

 when a second shallow emargiuation occurs, between which point and 

 its junction with the cheek the border of the ear is markedly convex 

 and projects forward from the base. 



Traijus. White, long and tapering to a point ( lengtji on the 

 inner side 7 mm.) : inner edge slightly convex, outer edge concave and 

 broadening towards the base near which there is a deep sharply-defined 

 emargiuation but no projection. 



Memhranes. Dark brown, unicoloured, naked. Wings, from the 

 base of toes. 



Far. Long and soft. Colour from specimens dried from spirit : — 

 male : hairs fuscous at base, then wood-brown followed by a daT-k brown 

 sabterminal annulation, the tips being ochraceous. Tiie latter colour 

 is most distinct on the extremity of the rump and on the head where 

 the top of the muzzle and the area between the ears are markedly 

 golden. Muzzle, except on the median line, and chin naked. 



Thumbs, feet, edg,' of wing along the second to the end of the 

 middle finger ; the dorsal side of the forearm, femur near the knee, 

 lower tibia, ankles, calcanea and tail, thinly but conspicuously clad 

 with shining ochraceous hairs. 



The female has the body pehige duller and darlcer than the 

 male, the wood-brown being replaced by dirty whitish, while the 

 ochraceous tips on the trunk are perhaps less pronounced and numerous. 



The characters of the skull and teeth appear to exactly agree 

 with those of the type, the cranium l)eing higher in the middle than 

 at the occipital region, the rosr.rum broad anrl heavy ; the upper 

 canine is very large and deejilj' grooved on tli> outer side with a pos- 

 terior cutting edge, and the lower lip is pitted to receive it ; the inner 

 lower incisors are four-cusped. 



Meusuremenis. External dimensions from spirit specimens : — 

 Head and body, 40 { 42.5 )* ; tail, 40 ( 38 ); tibia, 14.2 (15.2); 

 forearm, 32.3 ( 32.6 ) ; 2nd finger, 33 ( 30.-5 ) ; 3rd finger, 

 33.2 + 15.0 + 18.5 = 66.7 (33.0+14.4 + 10.7 = 67.1); 4th finger. 

 32.0 + 11.0 + 9.0 = 52.0 (31.3+11.0 + 9.5 = 51.8); 5th finger, 30.5 

 + 9.2 + 7.5 = 47.2 ( 29.5 + 8.8 + 8.0 = 46.3 ). Skull of male example :
