crest. There are prominent 

 supra-orbital ridges. The can- 

 ines of the males are very 

 large. The cervical vertebrae 

 bear very high neural spines, 

 on which are inserted the 

 muscles which support the 

 heavy skull. There are thir- 

 teen ribs, and seventeen dorso- 

 lumbar vertebrae. There is 

 no os centrale in the carpus. 

 There are no ischial callosities. 

 They live in families in the 

 forest, and feed on fruits. As 

 regards size, the gorillas are 

 most like man. The males 

 are much larger than the 

 females. 



The Chimpanzees {Anthro- 

 popithecus) live in Western 

 and Central Equatorial Africa. 

 They do not exceed » height 

 of 5 ft. The arms reach a 

 little below the knee. They 

 walk on the backs of their 

 closed hands and on their soles 

 or closed toes. The skull has 

 no high crests. The supra- 

 orbital ridges are distinct. 

 The canines are smaller than 

 in Gorilla or Orang. There 

 is no centrale in the carpus. 

 There are no ischial callosities. 

 The chimpanzees live in fami- 

 lies in the forest, and are 

 chiefly arboreal, making nests 

 in trees. They seem to feed 

 on fruits. In the sigmoid cur- 

 vature of the vertebral column 

 the chimpanzees are most like 

 man. 



In connection with the An- 

 thropoid apes may be noticed 

 Pithecanthropos erectus, a new 

 genus erected by Dubois from Fig. 



fragment of a skull and 

 femur found by him (fossil) 

 in Java, and alleged to re- 

 present a form intermediate 

 between man and the Anthro- 

 poid apes.
