THE MONA MONKEY. (Cercopithecus Mona.) 



The mona monkey, which is less frequently seen in England 

 than the preceding species, is a native of Guinea. 



It is a very beautiful and graceful creature. The crown of its 

 head is of greenish yellow tinged with black, and the neck, back, 

 and sides are of a bright chesnut brown, extending downwards as

 are snowy white j the outer surface of the legs and thighs are 

 speckled with black and grey 5 the hands and ears are of a livid

 is sometimes scarcely perceptible ; the tail is much longer than 

 the body, and has on each side of its base, or on the hips, a con-
