ioo APES, MONKEYS, AND LEMURS 



The general color of the fur is black, finely speckled with white, thus produc- 

 ing a grayish grizzle. In addition to the white beard and the crescent on the fore- 

 head, the cheeks, the chin, throat, chest, the front of the shoulders, as well as the 

 inside of the thighs and the streak across the haunches, are likewise white. On the 

 other hand, there is a broad streak down the back of a bay color, and the same tint 

 also prevails on the rump. The face, tail, and the outer sides of the wrists and legs 

 are black, as well as the hands and feet. 



All the colors of this animal are sharply defined from one another ; and the 

 long, narrow, black face, terminating below in the long and pointed beard, and 

 surmounted by the crescent above the eyebrows, give it a peculiar and character- 

 istic expression. The whole length of the head and body is about 18 inches, while 

 the length of the tail reaches to some 24 inches. 



The real name of the diana monkey in its native districts is said to be Roloway 

 on the Gold Coast, although Exquima is given as its title on the Congo. In dis- 

 position it is one of the most gentle and easily tamable of the guenons ; but, like 

 the greater number of its tribe, its temper is milder in youth than in mature age. 

 When young it appreciates caresses, and it nods and grins when pleased ; but these 

 expressions of feeling are generally abandoned at a later period. 



THE BEARDED MONKEY {Cercopithecus pogonias), CAMPBELL'S MONKEY (C. 

 campbelli}, THE RED-BELLIED MONKEY (C. erythrog aster} , AND WOLF'S 

 MONKEY (C. wolfi) 



We may notice under this collective heading four species of monkeys closely 

 allied to the mona, but distinguished both from that species and the diana by the 

 absence of any spot or streak of white on the haunches. While the first three 

 species are West African, the fourth, which has only recently been described from a 

 specimen living in the Zoological Gardens at Dresden, is from West Central Africa. 



The bearded monkey, also known as Erxleben's monkey, has the fur of the 

 upper parts either grayish or olive brown, finely grizzled with gray or yellow. 

 From above the eyes to the ears there is a black streak, while there is also a stripe 

 down the back of the same hue ; and the hands and feet, as well as the tail, are 

 likewise black. The forehead, the whiskers, the small moustache, and the under 

 parts of the body and the inner sides of the limbs are yellowish. This species has 

 been obtained from Fernando Po and the Gabun. 



Campbell's monkey, which inhabits Fernando Po and Sierra Leone, may be 

 distinguished by the absence of the black streak running from above the eyes to 

 the ears, and also by the whitish color of the under parts and inner sides of the 

 limbs. The general color is blackish olive, washed with yellow. 



The red-brown color of the chest and under parts, from which it takes its 

 name, is amply sufficient to distinguish the red-bellied monkey ; but as additional 

 characteristics, we may mention that the outsides of the thighs and legs are 

 grayish black, while the front of the thighs and the under surface of the tail are 

 grayish white.
