Quadrumana \Quad*ru"ma*na\, n. pl. [NL. See {Quadrumane}.]
   (Zo["o]l.)
   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.
