98 THE NATUBAL HISTORY OF 



MONKEYS OF ASIA AND AFRICA, OR 

 THOSE OF THE OLD WORLD. 



THE ORANGS. 



THE animals which have generally been placed in 

 this division are those, which of all creation, ap- 

 proach nearest to man in their structure. They have 

 generally been placed first in our systems, and we 

 have now to point out those characters important in 

 arrangement, and the distinctions which will separate 

 the species. They have been divided into three 

 genera, the first of which is named Troglodytes by 

 Geoffroy Saint Hilaire, and is characterised by a facial 

 angle of 50 ; distinct superciliary ridges ; the canine 

 teeth slightly elongated, and placed close to the 

 cutting teeth, as in man ; the head rounded ; the 

 muzzle short ; no tail, cheek pouches, or callosities ; 

 the ears resembling those of man, but large and pro- 

 jecting. It contains only one species.
