(narrow-nostril) 

 group, the for- 

 mer peculiar to 

 the New World, 

 the latter to the 

 Old World. The 

 higher apes and 

 "men are to be 

 associated with 

 the Old World 

 group. The tail 

 in many of the 

 South American 



monkeys is prehensile ; that is, it can be used 

 to hold on to a branch, as the animal swings 

 and leaps through the forest. In the Old 

 World no monkeys have a prehensile tail, and 

 in the anthropoid (manlike) apes or Simiidcz 

 there is no tail at all. 



(g) Artiodactyla, or even-toed ungulates (hoofed 

 animals). The (morphologically) third and 

 fourth toes are almost equally developed, the 

 others small or absent. This order includes 

 the following important families : 

 (i) Suidce. Pigs, na- 

 tives of the Old 

 World. 



(ii) Tayassuidce. Pec- 

 caries, the 

 American rep- 

 resentatives of 

 the pigs. 

 (iii) Hippo-potamidce. _
