THE YELLOW BABOON. 



CHAPTER III. 



APES, MONKEYS, AND LEMURS, continued. 



THE OLD WORLD MONKEYS AND BABOONS. 

 Family CERCOPITHECID^. 



ALTHOUGH there is some degree of uncertainty as to the precise significance to be 

 attached to the names Apes, Monkeys, and Baboons, we shall take leave to restrict 

 the former term to the Man-like Apes described in the preceding chapter, and use 

 the two latter for those other Old World Primates which do not belong to the 

 group of Lemurs. The name Monkeys is, however, also applicable to one family of 

 the Primates of the New World. Using, then, the terms Monkeys and Baboons in 

 this sense, we may mention, in the first place, that zoologists include the whole of 

 those inhabiting the Old World in a single family, for which they adopt the name 

 Cercopithecidce, taken from a genus of African monkeys. Our next point is 

 to consider how all these numerous species are to be distinguished as a whole 

 from the Man-like Apes on the one hand and from the American monkeys on 

 the other.
