MAMMALS COLLECTED BY DR. W. L. ABBOTT 233 



grizzled tawny-olive, bu££ tinged on chest. Feet and ears seal brown, 

 faintly grizzled. Shoulder stripes ill defined, dull ochraceous. Tail 

 glossy seal-brown above, irregularly lightened and grizzled, espe- 

 cially through terminal half, by the appearance at surface of the light 

 basal portion of the hairs. The basal portion of the hairs of the en- 

 tire tail is a bright golden yellowish brown. Above this color is 

 mostly hidden by the seal-brown tips, but beneath it forms a broad, 

 clear area extending from base to and including pencil, and only a 

 little darkened along extreme edge. Short hairs of under surface of 

 tail less yellow than others, slightly grizzled with brown. Autumn 

 pelage similar to summer coat but paler, the ferruginous of the back 

 and sides replaced by ochraceous. The new coat first appears on 

 shoulders and head, gradually extending backward and producing 

 peculiar contrasts with the darker and brighter summer pelage. 



Skull. — The skull of Tupaia ckrysomalla so closely resembles that 

 of specimens of T. ferruginea from Trong, Lower Siam, that I can 

 see no characters to distinguish them. 



Teeth. — The teeth are exactly as in Tupaia ferruginea. 



Meastiremoits. — External measurements of type : total length 330; 

 head and body 17S; tail vertebrae 152; pencil 30; hind foot 43 (40). 

 Average of three specimens from Pulo Jimaja : total length 315 (305- 

 330); head and body iSo (171-191); tail vertebra 146 (140-152); 

 hind foot 42.5 (42-43) ; hind foot without claws 41. 



Specimens examined. — Four : one from Pulo Siantan, the others 

 from Pulo Jimaja. 



Re?}iarks. — Except for the differences due to pelage, the four speci- 

 mens are very uniform in color. The yellow of the tail is occasionally 

 darker than in the type, approaching tawny-ochraceous, but never 

 tinged with red. Under surface of tail never grizzled as in T. pala- 

 ivanensis. 



MAGADERMA SPASMA (Linnaeus).

 (Asia.) 



Six specimens, two of which are skins, were collected on Pulo 

 Bunoa, Tambelan Islands, August 5-7, and one on Big Tambelan 

 Island. The color is faintly darker than in specimens from Trong, 

 Lower Siam ; but in size as well as in cranial and dental characters 

 the insular bats show no peculiarities.
