304 ZOOLOGICAL GARDENS. 
The colour of our animal is greenish yellow above, 
arising from the ringing of the hairs with various shades 
of yellow and black, but assumes more of a dark grizzled 
appearance on the sides of the body and outer sides of 
the limbs, which become gradually darker towards the 
hands. The face, ears, and naked part of the hands 
are of a jet black; the former is of a triangular shape, 
bounded above the eyes by a straight line of stiff black 
hairs, and on the sides by spreading tufts of hght hairs 
with a yellowish tinge, meeting in a point beneath the 
chin. The neck and chest are white, the under parts 
of the body have a yellowish tinge, and the inside of 
the limbs is gray. The length of the head and body is 
sixteen or eighteen inches, and that of the tail some- 
what more. 
Adanson has given, in his Travels in Senegal, an 
amusing account of the manners of these animals in 
their native state. In captivity they are generally cap- 
tious and malicious ; but much of their character, as in 
the other species, depends on their age and education.
