mandrill

The papio, the first baboon; the mandrill, the second; and the ouanderou, the third.

The mandrill has pouches on the sides of his cheeks, and callosities on his posteriors.

Another interesting baboon is the mandrill, which one does not often see in captivity.

Almost as odd-looking as the mandrill, though in quite a different way, is the gelada, which is found in Abyssinia.

So you see that altogether a grown-up male mandrill is a very odd-looking creature.
