32 WILD BEASTS OF THE WORLD 



large black ears, and yellow whiskers. The general colour of the coat 

 is olive-green above and white below. This pretty little animal is 

 unfortunately scarce, though a fair number have been imported of late ; 

 it comes from West Africa. 



THE MANGABEYS 



The Mangabeys (Cercocebus) are a small group of monkeys which are 

 considered to be intermediate between the Guenons and the Macaques. 

 They are large monkeys of slender form, with long tails, and dark- 

 ■coloured fur as a rule, which is not grizzled. Their faces have a very 

 pleasing expression as a rule; the skin is light-coloured, and their 

 upper eyelids are conspicuously white. 



They all inhabit Africa, and seem to have much the same habits 

 as the Guenons ; in captivity they live well, and are very active and 

 ■good-natured. Those most frequently seen are the Sooty Mangabey 

 {Cercocebus fuliginosus\ which is dull black shading into slaty below, 

 which is said to keep much on the ground in the wild state ; and the 

 White-collared Mangabey (C. collaris), which is slate-coloured above 

 and has a white collar and under-parts, with the crown of the head 

 bright red-brown, whence the name of " Cherry-crown " Monkey given 

 it by animal dealers. Both of these species are West African. There 

 are less than a dozen species of Mangabeys altogether, but these two 

 are among the best known of imported monkeys. There is at the 

 time of writing a very curious white Mangabey at the Zoo, which has 

 been described as a new species under the name of Jamrach's Mangabey 

 (C. jamrachi) ; it is not a complete albino, as its eyes are brown, 

 though its face and hands are flesh-colour; but it will very possibly 

 turn out to -be only a variety after all, since albino varieties do not 

 necessarily always show complete albinism by having pink eyes, as 

 we see with white dogs and cats, and with the White Lungoor of 

 Ceylon above mentioned.
