quadrumana

Quad*ru"ma*na, n. pl. Etym: [NL. See Quadrumane.] (Zoöl.) Defn: A division of the Primates comprising the apes and monkeys; -- so called because the hind foot is usually prehensile, and the great toe opposable somewhat like a thumb. Formerly the Quadrumana were considered an order distinct from the Bimana, which last included man alone.
