BlACK-TAILBD WaIiLABT. 



General form rather short and clumsy. Fur long, thick, and 

 rather coarse. General colour dark rufous grey, the rufous predo- 

 minating on the hinder back. Underfur long, soft, dark greyish 

 brown. Crown of head, round base of ear, outside of elbows, chin, 

 chest, and belly pale rufous, or yellow, the colour, however, very 

 variable both in extent and intensity, and often fading very much 

 in specimens long exposed to light. Face-markings, in the typical 

 variety, vague and indistinct, consisting of a dark-brown or blackish 

 whisker-mark from muzzle to eye, with a whitish cheek-stripe. 

 Ears short, coloured like the top of the head. Fore-quarters and 

 sides coarsely grizzled grey ; a broad mark just behind the elbow, 

 due to the absence there of the longer grey-tipped fur, and the con- 

 sequent showing through of the dark underfur. Hands and feet 

 brown, becoming black on the toes. Tail black, its proximal half, 

 sometimes grizzled with grey. 



Skull with large brain-case and comparative short face (facial 

 index about 220). Premaxillse short and upright, scarcely visible 

 from above beyond the tips of the nasals ; nasals long, narrow, and 

 straight-sided, slightly broadening behind, their central breadth 

 going about four times" in their length. Supraorbital edges sharp 

 and square, sometimes slightly overhanging, but not forming distinct 

 postorbital processes ; constriction fairly well marked. Infraorbital 

 foramen opening comparatively far from orbit, about 10 to 13 

 millim. distant. Palate with two large openings, each about as big 

 as the first two molars together. 



Teeth. Incisors (PI. IX. fig. 1) placed more vertically than in the 

 other species. I.' with the portion behind the notch decidedly shorter 

 than that in front. P.^ evenly oval, nearly as broad in front as 

 behind, about 7 miUim. long. P.* (PI. X. fig. 1) oval, very large 

 and heavy, recalling the corresponding tooth in Dorcopsis ; generally 

 longer than any of the molars, its outer side with three distinct 

 vertical grooves, and its inner with a broad cuspidate ledge. Lower 

 p.* about 8 millim. long.
