CHAPTER III. 
Apes, Monkeys, and Lemurs,— continued. 
The Old World Monkeys and Baboons. 
Family G EiicovruiECiBsE. 
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.
