Characters.—Face naked; tail moderately long, terminating in a tuft of hairs. General colour of fur olive-brown, or yellowish-olive, the hairs being ringed alternately with black and orange, or brownish-yellow, bars, for their outer third; body and outer surface of hind-limbs and tail olive-brown, the brown predominating; sides of head, under surface of body, and inner surface of limbs pale yellow; hands and feet dark brown or black—Length of body, 38 inches; of tail, 20 inches.
The canine teeth are very large, and the lower jaw very heavy. Distinguished from C. porcarius by its much lighter colour.
Distribution.—The interior of Abyssinia.
Habits.—This very rare Baboon, of which only a very few specimens are known, was brought by Schimper from Central Abyssinia. He states, according to Dr. Slack, that these animals are gregarious, as he met with them in troops of from one to two thousand individuals. They hunt their prey, which consists mainly of small Ruminants, in a manner similar to that of a pack of Hounds, following the quarry till it is exhausted by fatigue, and then capturing and devouring it. It is also stated that the Lion and the Leopard are unknown in the region inhabited by this Baboon. A glance at the animal under consideration would convince anyone that it is of a most ferocious disposition. Mr. Schimper also informs us that it wages continual war against the Gelada Baboon (Theropithecus gelada) which inhabits the same locality.
