502 QUADRUMANA. 



cheeks and throat are white, or dirty white ; the chest, the fore part of the 

 shoulders, the under parts of the body, and the inner side of the limbs, are 

 dirty yellow ; the inner side of the thighs is whitish ; the hairs of the tail 

 are brownish black. The fur is long and not very glossy ; that on the 

 head and fore parts of the body is the longest. There is no soft under 

 fur ; the hairs are of a uniform colour to the base, or, at least, are but very 

 slightly paler at that part. The portion of the back, which is described as 

 black, partakes in some degree of the rusty hue which prevails over the 

 other parts of the body ; it occupies only a narrow stripe of the dorsal 

 region, and blends indistinctly into the rust colour. The lower parts of the 

 limbs are removed, but as they are black at the knee, and also assume a 

 deep hue below the elbow, it is probable that the remaining portions are 

 black externally ; but internally, as far as can be seen, the limbs are 

 yellowish, or yellow white.

Two specimens exist in the museum of the Zoological Society, Lon- 

 don, Nos. 26 B, 26 B, a, of Suppl. to Cat. Mamm. 1839. Mr. Water- 

 house, in his account of this species, observes, that it is " the nearest yet 

 found to the Bay Monkey of Pennant, but that it differs in having the 

 throat and cheeks white, and in having three distinct shades of colour on 

 the body ; while in Pennant's animal, the cheeks are of a pale bay colour, 

 and the body is deep bay above, and pale bay beneath. It might be 

 argued that, by * deep bay,' Pennant meant to designate the peculiar 

 colour described by me as black with a rusty hue : if so, he could scarcely 

 apply the term ' very bright bay' to the parts which I call yellow. If, 

 however, even this were the case, there is still another distinct tint which 

 he has not mentioned, and that is the bright rusty-red colour of the sides 

 of the body and limbs. On the whole, therefore, I think I am right in 

 applying a name to the animal here described, which, it must be remem- 

 bered, is from a different locality ; viz., Fernando Po ; that of the Bay 

 Monkey being Sierra Leone. There is another circumstance which 

 should lead us to be cautious in pronouncing any species, which differs as 

 much as that here described, to be identical with Pennant's animal, since 

 it so happens that each red Colobus discovered has, in its turn, been 

 referred to the Bay Monkey, or to the Simia ferruginea of Shaw, which 

 is the same animal, and has had one or both of these names applied, and 

 subsequently changed upon the discovery of the next species ; in con- 

 sequence of which much confusion has arisen. I think we had better let 

 the Bay Monkey stand until we can find an animal agreeing with Pen- 

 nant's description." 



GENERAL HISTORY. It need scarcely be said that nothing is known 

 of the habits and manners of this species.
