32 MAMMALIA. 



* '.' 



GENUS VI. CYNOCEPHALUS.* 



Teeth very strong ; false cheeks ; callosities ; muzzle elon- 

 gated, and, as it were, cut off at the end where the nostrils 

 are pierced, which causes it to resemble that of the Dog ; 

 large size ; brutal and ferocious disposition. Our engraving 

 represents the dog-faced Baboon of Pennant, or Moco-Ape of 

 Buffon. A bluish ash colour ; hairs of the ruff, and especially 

 those of the sides of the head, very long ; face flesh coloured ; 

 of a horribly vicious instinct. [Arabia and Ethiopia.] 



TRIBE II. MONKEYS OF THE NEW CONTINENT. 



Six molar teeth on each side, and in each jaw ; no callosi- 

 ties nor false cheeks ; nostrils in the side of the nose ; tail 

 long, frequently prehensile that is, the extremity is capable 

 of seizing a body with much force by twining round it. Two 

 sections. 



Section /. CebitSj Erxl Sapqjous. 

 The tail prehensile. 



GENUS MYCETES, Illig. Howling Monkey. 



Head pyramidal ; face oblique ; lower jaw extremely large ; 

 the hyoid bone has a swelling or bony drum, which com- 

 municates with the larynx, and gives to the voice of these 

 animals an enormous volume and frightful sound. 



Section II. Pithecia, Desm., Illig. Sakis. 

 Tail not prehensile. 



FAMILY II. OUISTITIS. 



Incisive teeth to the number of four in each jaw, but oblique 

 and bent, especially in the upper jaw ; twenty molar teeth ; 

 no callosities nor cheek pouches ; tail bushy and not pre- 

 hensile ; nails compressed, crooked and sharp like claws ; 

 thumbs of the forehands movable, but placed with difficulty 

 in opposition to the fingers, from which, indeed, they are so 

 slightly separated that it is with hesitation we assign to them 

 the name of Quadrumana. They are pretty little creatures, 

 of agreeable forms and easily tamed. [South America.] 



* Dog-headed.
