APES AND MONKEYS. 
All the mangabeys have an oval-shaped head, with a somewhat long muzzle; 
and they may be readily recognised in the living condition by their white eyelids. 
Moreover, their hairs differ from those of the guenons in not being ringed with 
different colours. 
The Sooty Mangabey (Cercocebus fuliginosus). 
We select as our first example of these monkeys, the sooty mangabey, repre¬ 
sented in the accompanying woodcut. This monkey belongs to a group containing 
THE SOOTY MANGABEY (£ Bat. size). 
three out of the four species, and characterised by the hair of the crown of the 
head being directed backwards, without any prolongation into a crest. As its 
name implies, the fur of the sooty mangabey is of a deep and dull black hue; the 
chin and under-parts being ashy. The face is livid, marked with dark brown 
blotches about the eyes, nose, muzzle, and cheeks; the ears, as well as the palms of 
the hands and the soles of the feet, being of a blacker brown.
