n.
Large, short-tailed monkey ( Mandrillus leucophaeus , family Cercopithecidae).
Formerly found from Nigeria to Cameroon, it is now restricted to remote forest regions of Cameroon because of hunting and deforestation. Like the related mandrill , the drill is stout-bodied and has vividly coloured buttocks. The male is about 32 in. (82 cm) long and has a black face. Its lower lip is bright red, the hairs around the face and a tuft behind the ears are yellowish white, and the rest of the fur is olive-brown. An omnivore, it is mainly terrestrial, gregarious, and powerful, and it can fight ferociously if molested.
