102 ORDER II. 



prominent, powerful laniary teeth, and very broad 

 middle incisors ; large protuberances on each cheek 

 of the male, forehead much depressed, voluminous 

 beard, and chestnut-brown hair ; no eyelashes. And 



P. Abelii, or Red Orang, with long red hair, 

 that of the head extending upon the forehead in 

 the form of a periwig ; the eyelashes long ; muzzle 

 of the young short ; the adult as yet unknown. It 

 is, however, remarkable, that the very large, almost 

 colossal, male orang, whose skin, hands, feet, and 

 head were submitted to Dr. Abel's inspection, should 

 not have exhibited the fleshy protuberances of the 

 former species ; and, in the profile, it offered a much 

 more elevated forehead. Next we have the 



Hylobates gibbons, or Long-armed Apes, resem- 

 bling Pithecus in the length of arms, want of tail 

 and cheek pouches, but having a short muzzle and 

 decided callosities ; several are likewise of consider- 

 able size. Then follow the genera, 



Semnopithecus, or Solemn Apes, with very long 

 tails, and laryngeal saculi, but possessed of no, or 

 of small cheek pouches, and slender bodies; last 

 molar of lower jaw with five tubercles. 



Calobus, or Thumbless Apes, being destitute of 

 thumbs on the forehands : they have short muzzles ; 

 tail long and slender ; callosities and cheek pouches 

 always present ; last molar with five tubercles. 



Cercopithecus, Guenons, with muzzle slightly 

 elongated; tail long; have always callosities and 

 cheek pouches ; last molar of the lower jaw with 

 four tubercles only.
