 nostrils are forwardly directed and close together, being separated 

 by a narrow partition. 



The man-like or anthropoid apes (fig. 40), come nearest to

which are limited to the dense tropical forests of West and Central 

 Africa, the Orang-utan, of Borneo and Sumatra, and the Gibbons

 section of ape- like forms. They are provided with hard patches 

 (callosities) on the hind-quarters, and many of them possess cheek- 

 pouches in which, as known to all visitors of zoological gardens 

 and menageries, food can be temporarily stored. 



Of these tailed monkeys, one group includes tree-inhabiting 

 forms of comparatively slight build, a good example of which 

 is the Entellus Monkey, or Hunuman {Sem,nopithecus entellus)
