86 APES AND MONKEYS 



Its limits appear to conform more to isothermal lines than 

 to the rigid lines of geography. Specimens are sometimes 

 secured by collectors beyond these limits, but, so far as 

 I have been able to ascertain, they have been captured 

 within the territory thus bounded. There are several 

 centers of population. This ape is not strictly confined 

 to any definite topograph}", but occupies alike the upland 

 forests or the low basin lands. 



In one section he is known to the natives bv one name,

 idea of a lower order of human being. Among other

 allied to man than other animals are. 



There are two distinct tvpes of this ape. They are now 

 regarded as two species. One of them is distributed 

 throughout the entire habitat described, while the other
