sufficient to characterize it. The only discrepancy, he adds, observable 

 between the specimen and the description of the species (Col. polycomus, 

 or Full-bottom Monkey) given by Pennant, was in the great length of 

 the hairs of the body, which were generally four or five inches long : 

 this might be dependant on age or locality. 



The value of the white tail, as an evidence in favour of Mr. Bennett's 

 views, falls to the ground, when we know that this is also a character in 

 the Col. leucomeros ; besides which, the fur of the body, in no one 

 specimen yet examined, has been otherwise than long ; and there is no 

 reason to presume that it is ever different. 



Mr. Ogilby, when he described this species in the Proceedings of the 

 Zool. Soc. London, 1835, p. 98, had not then seen a perfect skin; those 

 from which he took his description wanting the head. Hence he 

 observes : " Whether or not this species, like the polycomus, has the 

 head of a different colour from the body, is a subject for farther observa- 

 tion ; the white or silvery hairs, about the neck and shoulders, render it 

 extremely probable that it has ; but in no case can it form the striking 

 contrast in length, nor present the long flowing mane, or wig-like appear- 

 ance ascribed to the animal observed by Pennant." The correctness 

 of Mr. Ogilby's remarks has subsequently been amply confirmed. 

 Respecting the locality of the present species, he adds, " Mr. Gould, 

 who procured these skins (viz., the originals of his description) for the 

 society, reported them as coming from Algoa Bay ; we know enough of 

 the zoology of that part of Africa, to render this account extremely 

 doubtful ; and the probability is, either that Mr. Gould was misinformed, 

 or that he may have mistaken Delagoa Bay for Algoa, which, from the 

 similarity of sound, might readily happen. If this conjecture should 

 prove correct, it would follow that the Colobus ursinus was the analogue 

 of the Colobus polycomus on the opposite coast ; and the conjecture 

 receives further countenance from the fact of many other known species 

 of mammals having such analogues in the same localities." Very for- 

 tunately, the locality of the species is now ascertained, so that all specu- 

 lation is at an end. The perfect skin, which we have described, was 

 brought from Sierra Leone, by the late governor (Major H. D. Camp- 

 bell), and Mr. Gould must have been misled. 



GENERAL HISTORY. Of the habits and manners of this beautiful 

 Monkey, no accounts have been obtained ; nor does it appear to have 

 been seen alive by European travellers ; the skins being purchased from 

 the natives of the wooded districts, who bring them to Sierra Leone for 

 the sake of barter.
