THE WHITE RHINOCEROS 147 



The skull and horns of an undoubted white 

 rhinoceros, shot by Major Gibbons at Lado, on 

 the Upper Nile, were exhibited at a meeting of 

 the Zoological Society, held on December i8th, 

 1900. Other corroborative evidence, were it 

 needed, is also forthcoming, showing incontest- 

 ably that Rhinoceros simus yet wanders over a 

 considerable portion of the African continent. 

 Dr. Gregory, in his work on the Great Rift 

 Valley, mentions having seen in Leikipia three 

 rhinoceroses, which he believed to be of this 

 species, though unfortunately none of the three 

 were obtained : Sir H. H. Johnston, in his work 

 on British Central Africa, states that a pair of 

 horns, resembling those of the white rhinoceros, and 

 obtained near the Ruo River, were sent home in 

 1895. The anterior horn was very long, slender, 

 and directed forwards (kabaoba P). 1 A number of 

 long slender horns were sent some years ago by 

 the late Mr. F. Holmwood and assigned to a 

 hypothetical Rhinoceros holmwoodi. They .have 

 not only been supposed to indicate a species allied 

 to the white rhinoceros but the kolmwoodi horn 

 now exhibited in the mammal gallery of the 

 Natural History Museum certainly recalls the 



i The forward inclination of the anterior horn is not however con- 

 fined to the white rhinoceros. The example of the black species in 

 the Berlin Zoological Gardens has the front horn pointing forwards 

 at an angle of 45 . On the other hand the black rhinoceros which 

 died in London in 1891 had the anterior horn vertical ; one thus has 

 " mohohu " and " kabaoba" forms in both species.
