" The monkeys are often divided into three groups: (a) Catarrhines, or Simidæ. These have an oblong head, with the oblique flat nostrils near together. Some have no tail, as the apes. All these are natives of the Old World. (b) Platyrhines, or Cebidæ. These have a round head, with a broad nasal septum, so that the nostrils are wide apart and directed downward. The tail is often prehensile, and the thumb is short and not opposable. These are natives of the New World. (c) Strepsorhines, or Lemuroidea. These have a pointed head with curved nostrils. They are natives of Southern Asia, Africa, and Madagascar." [1913 Webster]
