two species; viz., the Full -bottom Monkey of Pennant (Colobus 

 polycomus), and the Bay Monkey of Pennant, (Colobus ferruginosus), 

 neither of which have been seen by naturalists since the time of their 

 describer. Recently, Kuhl, Riippell, Ogilby, Waterhouse, and Van 

 Beneden have added to the list, which now consists of ten accredited 

 species; and of these, setting aside the Colobus polycomus, and C. 

 ferruginosus, which do not appear to exist in any museum, and the 

 Colobus verus of Van Beneden, which is only in the Museum of Paris, 

 fine examples enrich the museum of the Zoological Society of London. 



It is scarcely necessary to add, that the Colobi are as exclusively 

 peculiar to Africa, as are the Semnopitheci to the hotter regions of Asia. 

 Of the exact locality of one species, we are still ignorant ; with regard 

 to the rest they belong, respectively, to the borders of the Gambia, to 

 Sierra Leone, and the island of Fernando Po, on the west, and to Abys- 

 sinia, on the east of that mighty continent.

GENERAL HISTORY. Our knowledge of this species is exclusively 

 derived from Pennant, who is its only original describer ; and it is from 

 his figure and account, both taken from a skin which came under his 

 notice, and which formed part of the celebrated Leverian Museum,
