36 Lloyd's natural history. 



sparse hairs are parted down the middle. Length, 27 inches ; 

 tail, 24 inches, but often proportionately longer. 



General colour of the back and the upper side of the tail 

 brownish-olive; outside of the limbs greyish — the hairs grey at 

 the roots, ringed higher up with dull yellow and black bars ; 

 under surface of the body and inside of the limbs, and under 

 side of the tail whitish ; face, ears, callosities, and other nude 

 parts livid flesh-colour. 



Skull long, lower than that of M. rhesus ; orbits with the 

 transverse diameter greater than the vertical. 



Distribution — Inhabiting all Southern India, being conter- 

 minous with the M. rhesus on the east and west coast, the 

 latter species coming as far south as, and the Bonnet Macaque 

 going no further north than, the Godaveri river on the one 

 side and Bombay on the other. (See page 23.) 



Habits. — The Bonnet Macaque agrees in habits with those of 

 the species already described. It lives in troops in the forests 

 and jungles everywhere throughout its range. It is much kept 

 in captivity, owing to its docility and its wonderful powers of 

 mimicry. 



THE MANGABEYS. GENUS CERCOCEBUS. 

 Cercocebus, Geoffr., Ann. Mus., xix., p. 97 (1812). 

 This genus has been established to receive a small, and but 

 little known, group of Monkeys, which is confined to West 

 Africa. They are nearly related to the Macaques on the one 

 side, and even more closely to the genus Cercopithecus^ next to 

 be described, on the other side. They all have an oval head, 

 and in form are more slender than the Macaques; they have also 

 the muzzle less prolonged, the supra-orbital ridges less devel- 

 oped, the ischial callosities larger, and the limbs oroportionately
