THE ANTHROPOID APES 



In Group I., the CATARRHINI, are all the apes and monkeys 

 of the Old World. The group possesses certain charac- 

 teristics that cannot 

 be mistaken. In 

 a few cases the 

 thumb of the fore

 whenever it is pre- 

 sent it is opposable; 

 the nostrils are 

 placed close to each 

 other, and the tail, 

 if the animal possess 

 one, is never prehen- 

 sile.

 Anthropoid apes, 



more closely resemble man than any other branches of 

 the Quadrumana. In the family are only the gorilla, the 

 chimpanzee, the orang-outan and the gibbons. All four are 

 arboreal in habit, and consequently the old name troglodytes 

 (cave-dwellers) was never really applicable to them.

The Gorilla, the largest and strongest of the Anthropoid 

 apes, has its home only in the hottest parts of West Africa, 

 particularly in the damp, shady forests between the Congo 

 and the Niger. In all probability the whole area of its 

 habitat does not exceed a thousand square miles. The
