CHARACTERS.--Snout very elongated; nape of the neck crested. Face black;
general colour uniform olive-green; the hairs being grey at the base and
ringed higher up with bars of black and yellow; arms and legs like the
back; the naked hands and feet flesh-colour.
DISTRIBUTION.--Interior of West Africa. Lagos, in the Bight of Benin, is
the port from which this species is generally shipped to Europe.
HABITS.--The Anubis Baboon is not a common species in captivity, as the
natives are terribly afraid of its strength and ferocity. The animals
wander about in companies, inhabiting chiefly the dry, rocky, mountainous
regions in the interior of West Africa, feeding on the peculiar vegetation
that they find there; digging up the roots of grasses, and gnawing with
their strong jaws the roots and stems of an extraordinary short, woody,
top-shaped plant, known as _Welwitschia_, which produces in its youth two
leaves, and never more in its lifetime, though attaining to a great age.
They feed also on the _Scytonema_, a moisture-storing plant, which grows
only on rocks. Though affecting dry, rocky regions from choice, the Anubis
Baboons often descend in large hordes to the cultivated country, and ravage
the gardens of the natives.
Mr. Darwin, in describing the expression of pleasure, joy, and affection in
Monkeys, observed that, when they were pleased, the form of the lips
differed a little from that when they were angered. In the case of an
Anubis Baboon which was first {268}insulted and put into a furious rage by
his keeper, who afterwards made friends with him, Mr. Darwin relates that,
"as the reconciliation was effected, the Baboon rapidly moved up and down
his jaws and lips, and looked pleased. When we laugh heartily, a similar
movement or quiver may be observed more or less distinctly in our jaws; but
with Man the muscles of the chest are more particularly acted on; whilst
with this Baboon, and with some other Monkeys, it is the muscles of the
jaws and lips which are spasmodically affected."
