doubt affords a pleasant change of diet when the young corn is 

 beginning to appear." 



An oribi from near the north end of the Albert Nyanza has, 

 however, been provisionally referred to this species, which may occur 

 also in the Kavirondo district. 



GOSLING'S ORIBI 



( Oribi a goslingi) 



An oribi from the upper part of the Welle Valley, in Congo 

 territory, described by Messrs. Thomas and Wroughton in the Annals 

 and Magazine of Natural History for 1907 (ser. 7, vol. xix. p. 387), 

 agrees in size with hastata, being larger than kenycE, and having longer 

 horns than montana, while it is further characterised by the presence 

 of a conspicuous black patch on the forehead between the horns and 

 extending to the base of the ears. The coat of the back has a darker 

 tinge than in other species. 



With the exception of a smaller one in a specimen referred to 

 inontana, no other oribi but the Cape species has a similar black patch 

 on the forehead ; and geographical considerations indicate the distinct- 

 ness of these two animals. The larger size of its skull distinguishes 

 the present species from both inontana and kenyce ; while from hastata 

 the species is differentiated by certain peculiarities in the form of the 

 skull as well as by the black horn-patch. 



COTTON'S ORIBI 



{Oribia cottojii) 



Under this name Mr. O. Thomas has described in the Annals and 

 Magazine of Natural History for 1908 (ser. 8, vol. i. p. 177) an oribi 

 brought home by Major Powell-Cotton from the Guashengisha plateau 

 (lat. 1° N., long. 35° E.), in Central Equatorial Africa. It is described 

 as being about the size of Oribia goslingi, but with the fur rather longer, 

 and the general colour paler and brighter above, being tawny fading 

 to buff on the flanks, whereas in the western species it is dark clay 

 fading to ochery. Individual hairs of the back are drab for the basal 

 two-thirds, and buff for the remainder of their length, with minute 

 black tips ; while in goslingi they are pale smoke -grey below, and
