120 COLO BUS 



GEOGRAPHICAL DISTRIBUTION OF THE SPECIES AND SUBSPECIES. 



The members of the genus Colobus are pretty evenly divided 

 between the east and west coasts of Africa, in the central portion of 

 the continent, being found from Abyssinia to Nyassaland on the east, 

 and from Gambia and Lake Chad, Nigeria, to Angola on the west. 

 Beginning with Abyssinia, in the Province of Godam and Kulla of the 

 south and west, C. abyssinicus is found, ranging eastward probably 

 into Somaliland ; while in the forests through which the Omo flows C. 

 POLiURUS dwells, and in the vicinity of Harrar at Abassie not far from 

 the Somali border, C. gallarum was discovered, the extent of its 

 range, however, unknown. Passing southward to the west of Lake 

 Albert on the borders of Uganda and the Congo State the undescribed 

 form in the Berlin Museum, from Avakubi, Lake Albert, is met with, 

 and west of the north end of Lake Albert Edward, C. ellioti was dis- 

 covered. On Mount Ruwenzori, at an elevation of 4,000 feet, C. 

 TEPHROSCELES was found, and on the north west flank of the same 

 mountain, in the country of the Buambas, C. ruwenzori was obtained. 

 In the vicinity of Mt. Kenia, C. caudatus was met with, and it extends 

 its range to Mt. Kilimanjaro in German East Africa. At Muniuni, 

 near Mombassa, C. rufomitratus was discovered, and opposite Zanzi- 

 bar C. PALLiATUS was fouud, its range not yet ascertained. C. kirki 

 is restricted to the Island of Zanzibar, never found on the mainland, 

 and now nearly extinct. Between Lake Tanganyika and the Upper 

 Congo, C. FOAi ranges, and west of the same great lake, C. graueri 

 was taken at Wabembeland. In the Ituri forest, and southward to 

 the Tanganyika-Nyassa Plateau, C. sharpei ranges. In German East 

 Africa at Udschumgwe Berge, C. godonorum is found. 



In West Africa commencing at the most northern part where any 

 species of Colobus dwells, we find in Senegambia, C. bouvieri ; C. 

 FULiGiNOSUs; and C. vellerosus ; the last ranging to the Gold Coast, and 

 C. satanas going to the Gaboon. In Sierra Leone C. ferrugineus is 

 found going into Liberia, while in the southern portion of Sierra Leone, 

 C. rufoniger is also met with, and C. polycomus going to Liberia. 

 Fantee and Ashantee have C. veru.s, which is also stated to inhabit Li- 

 beria. In Nigeria from Lake Chad, through Central Africa along the 

 Upper and Lower Congo to Victoria Nyanza, C. occidentalis has its 

 range. At Barombi in Cameroon, C. preussi was found ; while in the 

 Congo River forest were obtained C. nigrimanus at Lirranga. C. 

 oustaleti in the Youmba country, and C. tholloni, exact locality not
