Female and Young Male.—Facial rugosities less marked outwardly, as well as on the skull, than in the adult male, and the purple colour of the grooves wanting. The nose is black, not scarlet.
A hybrid between a female of this species and a male Macaque (M. cynomologus) was born in the Zoological Gardens of London in October, 1878.
Distribution.—West Africa, from Senegambia to the Congo.
Habits.—These hideous and extraordinary animals live together in large companies, and are a terror to the natives. They are less ill-dispositioned when young, but when adult, they are very savage. They are nearly omnivorous, but fruits and insects form their chief food. When the Mandrill is in any way excited, the brilliantly-coloured naked parts of the skin are said to become still more vividly coloured.
