The monkeys which most closely resemble man in structure, habits, and intelligence, are the so-called anthropoid apes, the gorilla, the chimpanzee, the orang-utan, and the gibbon. A second grade is represented by the more dog-like, narrow-nosed Old World apes, such as the baboons and mandrills. Lower in many ways are the broad-nosed New World or American monkeys, the numerous species of Cebus, some of which are the familiar.
