52 QUADRUMANA. 



The Hussar ape extends from the West Coast of Africa to Abyssinia, 

 but is much rarer than the Green apes. It is found in low thickets or 

 tall grass, with which the color of its coat harmonizes. In character it 

 is the very opposite of the Green apes. Its countenance is morose and 

 unfriendly, and its actions do not belie its looks. Especially as it grows 

 older, does its temper become more irritable ; it never enters into 

 friendly relations with other animals, not even with other apes ; every- 

 thing seems to annoy and provoke it ; a look excites anger ; laughter 

 arouses rage and fury. Then it displays its immense teeth, and, if 

 o^:)portunity serves, makes use of them on the observer. Kindness is 

 thrown away, severity makes the creature worse. An adult Hussar ape 

 has never been seen tame. 



III.— GENUS CERCOCEBUS. 



This genus forms the transition between the Cercopithecus and the 

 Macacus, and the name of Mang.vbey is usually given to the animals 

 embraced in it. They are almost the same size, and have nearly the 

 same gait as the Guenons : but they are not so nimble. Their tail is 

 long, and they usually carry it raised above their backs. Their habits 

 differ but little from those of the majority of the Macacus, and they 

 scarcely offer anything more distinctive in their character. All that can 

 be positively asserted is tliat they are more gentle and familiar. 



THE MANGABEYS. 



The Moor Ape or Common Mangabey, Cercoccbus fuliginosus, is the 

 best known representative of this genus. It attains a considerable size, 

 a little over four feet, including two feet of tail. The color on the back 

 is a dull black, on the stomach and the inside of Ihe limlis a dirty gray. 

 The face and hands are black, and a peculiar look is given by the con- 

 trast of the upper eyelids, which are pure white. 



The species Cercoccbus collaris differs from the above by having 

 the top of the head of a dark chestnut hue, the cheeks snow-white, the 

 rest of the body a dull black. Both species come from the West Coast 

 of Africa. 



Among the peculiar habits which distinguish the Mangabeys, we may
