district of the Gambia, Western Africa ; and it is from this (No. 26 A, 

 Catalogue Mamm. Suppl. 1839) that we have taken our description. 



The other two are the skins (No. 26 A, a, Catalogue Mamm. 

 Suppl., 1839) referred to by Mr. Bennett in the Proceedings of the 

 Zool. Soc. Lond. 1832, p. 122, and considered by him to be those of 

 the Colobus ferruginosus (or Bay Monkey), when, as he adds, at the par- 

 ticular stage in which it is " described by M. Kuhl, under the name of 

 Colobus Temminckii," Mr. Bennett, evidently regarding the latter as a 

 mere variety of the former. To the same specimens Mr. Ogilby also 

 subsequently alludes in the Proceedings of the ZooL Soc. Lond., 1835, 

 p. 99, observing, "notwithstanding some slight discrepancies, I agree with 

 Mr. Bennett, in referring to the Colobus Temminckii, Kuhl (regarding it, 

 however, as truly distinct from Colobus ferruginosus), the two other skins 

 noticed by him in the part of the Proceedings already referred to. These 

 skins were procured at the same time, and, most probably, in the same 

 locality as those of the Colobus ursinus ; they were equally imperfect ; 

 the hair of the shoulders and back is dead black, and without the beautiful 

 gloss so conspicious in the Colobus ursinus ; on the ^flanks, and over 

 every part of the limbs, the colour is uniform maroon, or clear purple 

 red ; the head and hands are wanting ; but the maroon of the tail is 

 much deeper than that of the legs and flanks, approaching almost to 

 black ; and in the older of the two specimens it is actually replaced by 

 that colour on the terminal half of the tail." 



Recently, however, Mr. Ogilby has had reason to alter his opinion, 

 and to regard the skins in question as belonging to a species equally as 

 distinct from the Colobus Temminckii, Kuhl, as this is from the Colobus 

 ferruginosus. 



The locality in which they were said to be obtained, viz., Algoa, or, 

 with a query, Delagoa Bay, is evidently incorrrct. The specimen pre- 

 sented by Mr. Rudge, came, without doubt, from the region of the 

 Gambia, which may be regarded as the habitat of the species. 



GENERAL HISTORY. As is the case with all the Monkeys of this 

 genus, one alone excepted, nothing is known of the habits and manners 

 of the present Colobus.
