According to Col. Sykes, “ The manners of this monkey are grave and sedate. Its disposi¬ 
tion is gentle, but not affectionate; free from that capricious petulance and mischievous irascibility 
characteristic of so many of the African species, but yet resenting irritating treatment, and evinc¬ 
ing its resentment by very smart blows with its anterior hands. It never bit any person on board 
ship, but so seriously lacerated three monkies, its fellow-passengers, that two of them died from the 
wounds. It readily ate meat, and would choose to pick a bone, even when plentifully supplied 
with vegetables and dried fruits.” 
For the anatomy of this species, see Professor Owen’s paper above referred to. 
The exact locality from whence this species of monkey is procured remains doubtful. 
Col. Sykes believed it came from Madagascar; I have since been informed that it inhabits the 
Island of Zanzabar, east coast of Africa. 
The Cercopithecus albogularis belongs to that section of the Cercopitheci of which the 
Cere, sabceus may be considered as the type. 
The whole of the upper surface of the animal is of a mingled black and yellowish ochre 
colour, each hair being annulated with black and ochre; the black prevailing on the shoulders, 
the ochre on the back and flanks; under surface, grizzled, white and black; anterior limbs, uni¬ 
form black; posterior, black, with a little of the dorsal colour; chin and throat, pure white; tail, 
black. 
Length of the head and body, two feet two inches; tail, two feet six inches.
