This is a uniformly brownish-black monkey, the limbs, 

 head, and tail being almost wholly black, but the difference 

 between the colours is not well defined, and the fore limb is 

 grizzled with whitish hairs. The tail is slightly bushy at its 

 extremity. There is a rather short, vertical crest directed 

 backwarils, the hair anterior to it projecting forwards over the 

 eyebrows. The ears are nioderatelv la:"ge and partially ex- 

 posed. Tbe hail- on the front and side of the head and on the 

 middle of the crest is blackish oi" dull brown. The upper lip 

 and chin are clad with short whitish hair, with longer black 

 hairs intermixed on the chin. Along the flanks the hair is 

 short, sparse, brown, and somewhat grizzled, which is the 

 character also on the abdomen. The throat, sides of the neck 

 and chest are concolorous with the upper parts. A narrow, 

 well defined white line jiasses along the middle ot the under 

 surface from the chest in the adult to the hinder portion ot 

 the abdomen, but in the young specimens this line is obscure, 

 as the throat, chest, and abdomen are yellowish white, and 

 where it dies away on the inside ot the limb, the white line is 

 prolonged as a fine line t.> tlie wrist and ankle. In the adult 

 the brachium is greyish, bat there is a distinct teutlency \asible 

 to the formation of a narrow obscure greyish line along the 

 inner aspect of the antibrachium, but of \'ariable intensity. 

 The inner sides of the thighs are also white or pale grey, 

 and this colour extends a short way below the knee. The iace, 

 ears, and the palms of the hands and sides of the feet black.
