500 QUADRUMANA. 



Colobus fuliginosus, which term sinks into a synonym of Colobus Tem- 

 minckii, Kuhl. 



The original of Kuhl's description was formerly in Bullock's Museum, 

 but is, at present, in that of Leyden. With respect to the locality of this 

 species, it is now ascertained to be Gambia, whence the specimen described 

 by Mr. Ogilby was brought by Mr. Kendall (1835); others have been also 

 received from the same district ; the settlement of this point is of the 

 more value, inasmuch as the locality whence Kuhl's original specimen 

 was obtained is unknown. 



In a very young example of this Colobus, recently examined, the 

 fur of the back, which is of a deep, sooty, slate colour, is obscurely 

 freckled with yellowish, each hair having a minute annulation of this 

 tint : on the occiput) as in the adults, a marked transverse line is seen, 

 where the hairs are more freely annulated with rust colour, communicat- 

 ing to this part a general rufous tinge : an abrupt yellow streak runs 

 down each side of the body. The under parts are very thinly clad with 

 silky white hairs ; the tail is a dirty yellow at the base, rust coloured at 

 the apex ; the hind toes are all united as far as the first joint. 



GENERAL HISTORY. Nothing has been collected relative to the history 

 of this species as it exists in a state of freedom.

 Colobus rufo-niger Catalogue Mamm. Zool. Soc. Suppl. 26 A, and 26 A, a. 1839. 



SPECIFIC CHARACTERS. Colour of the upper parts, and of the sides of the humerus and 



thighs, black ; sides, and under part of body, chestnut red. 

 LOCALITY. Gambia, Western Africa. 



DESCRIPTION. The head and the back are black, which colour 

 extends over the outer side of the humerus, and of the thighs ; the tail 

 is black, with a tinge of chestnut ; the whole of the under surface is 

 maroon, or chestnut red ; the knees are also chestnut red ; and, as far 

 as admits of being traced, this is the colour also of the fore-arms and 

 legs ; the specimens, however, being imperfect in the extremities, it is 

 impossible to say whether the colour is pure and bright, as in Colobus 

 Temminckii, and, according to Pennant's description, in Colobus ferru- 

 ginosus ; or more or less clouded with black : the fur of the body is long 

 and soft ; size that of Colobus Temminckii. 



Three distinct specimens, imperfect in the limbs, exist in the museum 

 of the Zoological Society of London : one is a late acquisition to the 

 museum ; it was presented by Edward Rudge, Esq., and obtained in the
