Perm slender; the face broad across the eyes, but compressed from above 

 downwards ; the trunk of the body dark-yellowish brown, with a tinge of red 

 on the flanks in some individuals, but passing into dark brown and then into black 

 on the greater part of the outside of the limbs, on the back part of the thighs and 

 on the root of the tail ; the remainder of the tail being greyish or yellowish brown 

 and tufted. The neck and head are yellow-brown, but the latter colour passes into 

 black on the haired portion of the forehead, sides of the head, and on the crest. 

 The under parts are pale reddish, lighter on the throat, extending as a narrow band 

 down the inside of the fore-limbs to near the wrist, and also on the hind limbs, but 

 stopping short of the ankle. A bald, triangular area between the eyebrows, ascend- 

 ing to the middle of the forehead and in reality occupying the glabella, reaching at 

 its upper end that part where the radiation of the hair of the other species usually 

 takes place, of a milky-white colour and wrinkled ; the rest of the face being deep 

 black, except the lower lip and a narrow line along the upper lip which are flesh- 

 coloured and sparsely covered with yellowish brown hairs. Along the upper margin 

 of the bare area are arranged long and black hairs, which, being directed downwards 

 and outwards, commingle with the long, bristly, black eyebrows, and reach as far 

 back as the ears, as a marked lateral tuft or pencil, the hair on the side of the 

 head above these lengthened hairs being short. The hairs on the cheeks from 

 near the nose along the malar region to the anterior root of the zygomatic arch 

 are long and black, increasing in length on the hindmost part of the cheek to 

 such a degree that they depend nearly to the shoulder. The crest is erect, high 

 and compressed, occupying the middle line of the head like the ridge of a helmet, 

 over-arching the forehead, where it is slightly contracted, and reaching backwards 

 to the occiput, where it decreases and mingles with the hairs on the upper part of 

 the neck.
