muzzle blackish in front of the eye ; from the occiput two conspicuous white marks run backward, and 
diverging, pass one on each side over the shoulder, and recurve at a short distance behind the insertion 
of the fore-leg ; the space between these lines is black on the occiput, and brownish black on the back of the 
neck ; sides of the neck suffused with pale ochreous yellow ; tarsi and arms nearly white ; hands and toes 
dusky, but most of the hairs round the nails of the former white ; tail coloured like the body at the base, 
hut black along the upper surface of the apical third, and at the point where the hairs being longer than 
elsewhere, hide a small horny tubercle with which the tail is terminated ; under surface of the tail dirty 
yellowish white. 
The female is not distinguished by any difference in marking ; the stripes are quite as intense as in the 
male, and are even apparent in the foetus. 
Considerable variation occurs in the weight of individuals, and particularly in the size and w'eight of the 
sexes, fully adult males weighing from ten to twelve pounds, while the females do not exceed four or six.
