RATUFA PALLIATA Miller. 



1902. Ratufa palliata Miller, Proc. Acad. Nat. Sci. Phila., March ,1902, p. 147; 

 issued June 11, 1902. 



Type.— Adult male, skin and skull, Cat. No. 113162 U.S.N.M., col- 

 lected along the Indragiri River, southeastern Sumatra, September 23, 

 1901, by Dr. W. L. Abbott. Original number, 1327. 



Diagnostic characters. — Very similar to Ratufa hicolor from Java, 

 but hind foot apparently larger; upper parts without the light speck- 

 ling usually seen in R. hicolor, and tail never appearing clear buff, 

 but an indefinite mixture of dark l^rownish and buffy, often appearing 

 annulated. The light yellowish brown mantle mentioned in the 

 original description as characteristic, while often present is not found 

 to be a constant feature in all the examples of this species that have 

 been collected by Doctor Abbott since the original account of the 

 species appeared. 



Color. — Upper surface of head and neck, shoulders and rump, and 

 outer surface of fore and hind legs and fore and hind feet, blackish or 

 dark brown; color of back between shoulders and rump, variable; 

 in the type and some other specimens, dark cream-buff, becoming 

 clay-color in the middle line, while in other individuals the middle 

 line of the back has the general effect of Ridgway's seal brown, gener- 

 ally blending with the cream-buff color of the sides. Sides of head 

 and neck, shoulders, and sides of body, as well as inner side of foreleg 

 and a spot just above wrist, cream color, or cream-buff, and, except on 

 the sides, contrasting with the black of the head, neck, etc. Under- 

 parts and inner side of hind legs generally cream-buff, but the dark 

 bases of the hairs show to a considerable extent. Hairs of the tail, 

 blackish-brown, lighter at the base, with a broad (6 mm.) subterminal 

 cream or cream-buff ring and an inconspicuous brownish apex. The 

 two colors of the tail are about equally prominent, and usually so 

 arranged as to give the- tail a somewhat annulated appearance. 



A very young individual. Cat. No. 114547 U.S.N.M., from Tapanuli 

 Bay, evidently in its first pelage, long and soft, deviates somewhat 

 from the color pattern just described. The mantle is well devel- 

 oped, varying between a light clay color and ochraceous buff; 

 the black of the head, neck, rump, and thigh is largely replaced by a 

 color between hazel and chestnut; this color extends on the base of 

 the tail, above, and is again indicated at the tip of the tail; the middle
