The Mangaheys inhabit the interior of Africa. Up to the 
present time only three species have been found. 
Tribe of Guenons. — The Guenons are slender Monkeys, which 
have the cranium depressed, and show no forehead — at least at 
an adult period of life ; they have large paws, marked callosities, 
long, sharp canine teeth, well-formed extremities for prehension, 
a long elevated tail like the Mangaheys, and a thick and more or 
less speckled coat. Naturalists usually designate them by the 
name of Cercopitheci, which means Tailed Monkeys (/cep/cos, tail, 
mOr]Ko<s f Monkey). The genus Guenon comprises about thirty 
species. 
These animals live in troops in the forests ; they are constantly 
moving about from tree to tree, and with an extraordinary facility 
execute the most wonderful capers. In each troop there is a sentry 
entrusted to watch over the general safety. On the appearance 
of an enemy, this vidette gives a particular cry, and all the 
band, collecting in the highest places they can find, at once pre- 
pare to repel the intruder. Fruits and branches are then hurled 
down at the aggressor, who, disarmed and helpless against this 
aerial horde, is soon compelled to take to flight. The negroes 
find these kinds of skirmishes but little to their taste, and, there- 
fore, rarely trust themselves in those parts of the forests where the 
Guenons have established their domicile. The largest quadrupeds, 
not even excepting the Elephant, are not exempted from these 
attacks, and find it advisable to evade by flight the disagreeable, 
if not dangerous, consequences of such conflicts. There are only 
two beings capable of contending successfully with them : these 
are Man, with his bow or firearm, and the Serpent, which creeps 
in the darkness, to the highest branches of the trees, and in this 
way contrives to circumvent and seize these dwellers of the 
forests. 
The food of the Cercopitheci is varied : they chiefly live on 
roots, leaves, and fruits. They also eat the eggs of birds, insects, v 
sometimes even molluscs, and they are particularly partial to 
honey. They devastate gardens and plantations, and appear 
impelled to commit these acts of brigandage as much from
