Nannosciurus pulcher s^p- nov. 



' Type— Adult female (skin imd .<kull), No. 11.3,131 Unileil 

 States National Museum. Collected on Sinkep Island, Soul h'China 

 Sea, September 4, 1901, by Dr. W. L. Abbott. Original num- 

 ber 1,274. 



Characters. — Like Nannosciurus melanotls Miiller and Schlegel, 

 but back paler, belly more oehraceous, and light nuchal patch very 

 distinct. ' 



Color. — The colors of this squirrel are dilHcult to describe, as 

 thev cannot be exactly matched in Ridgway's Nomenclature. The 

 back, sides, and outer surface of legs rather closely resemble wood- 

 brown, with a tinge of olive and a scarcely perceptible grizzle caused 

 by the black tips of the hairs, but the brown itself is more nearly a 

 pale raw umber. Crow^n similar to back, but strongly tinged Avith 

 russet. Nape whitish, in strong contrast with surrounding parts, 

 the hairs faintly tipped with black. Inner surface of ear rather 

 thickly sprinkled with hairs in color similar to back. These extend 

 over anterior border of outer side of ear, but the remainder of the 

 outer surface is black, continuous with an elongated black patch 

 which lies behind ear and sends back a narrow, ill-defined border 

 to whitish nape patch. Side of head with yellowish white line 

 about 3 mm. in width, beginning at side of muzzle just above 

 nostril and extending back to a point slightly behind posterior border 

 of ear. This stripe includes lower eyelid. From inner canthus of 

 eye to muzzle it is faintly bordered with black. The stripes of the 

 opposite sides are separated on muzzle by a space of about 2 mm. 

 Under parts, feet, and inner surface of legs a pale tawny, closely 

 approaching the ochraceous-buff of Ridgway, but somewhat more 

 yellow. Tail a uniform coarse grizzle of tawny, black and white, 

 each hair with six color bands. These are as follows, beginning at 

 base: (1) Tawny, 2 mm.; (2) slate-gray, .1.5 mm. ; (3) tawny, 

 4 mm. ; (4) black, 5 mm. ; (5) white, 3 mm, ; (6) black, 1 mm. 

 At tip the pattern changes to 10 or 11 alternating bands of black 

 and tawny, the black terminal area increasing to 7-10 mm. As a 

 residt the white element of the grizzle is absent in this region. 



Skull and Teeth. — The skull and teeth apparently resemble those 

 of N. xohiteheadi rather closely, except that the rostrum is less 

 elongate and the upper incisors less projecting forward. The speci- 

 mens of both species at hand are, however, in poor condition. The
