Habits.—This Monkey is very frequently brought alive to Europe, and almost all that we know of its habits has been obtained from observing it in captivity. Colonel Sykes, who first brought this species to England and described it, says that "its manners in captivity are grave and sedate. Its disposition is gentle, but not affectionate; and though free from that capricious petulance and mischievous irascibility characteristic of so many of the African species, still it quickly resents irritating treatment, and evinces its resentment by very smart blows with its anterior hands. It never bit any person on board ship, but so seriously lacerated three Monkeys, its fellow passengers, that two of them died from the wounds. It readily ate meat, and would choose to pick a bone even when plentifully supplied with vegetables and dried fruits." Another individual, seen by Mr. Ogilby, exhibited the same antipathy to other Monkeys.
