Word Origin and History for mandrill
n.

"large baboon," 1744, perhaps ultimately from an African language, but formed into English components man + drill (n.4) "baboon," which is of W.African origin. The earliest reference reports the name is what the animal was "called by the white men in this country" (Sierra Leone). French mandrill, Spanish mandril seem to be from English.
