658 MR. P. L. SCLATER ON THE RHINOCEROSES 
that Mr. Blanford! has identified the Rhinoceros of N.E. Africa with 2. keitloa?. But 
in the Rhinoceros at Berlin, of the head of which I exhibit a drawing kindly procured 
for me by Dr. Peters (fig. 9), the horns would appear to be much more nearly like 
those of &. bicornis ; and we must recollect that that came from exactly the same district 
as our specimen. I have also seen other examples of Two-horned Rhinoceroses clearly 
intermediate between the two forms.

Under these circumstances I have thought it better for the present to let our Rhino- 
ceros stand under the name J. bicornis. At the same time, 1 think it highly probabie 
that, when more specimens have been obtained and the subject has been more 
thoroughly investigated, ample difference will be found to exist between £. bicornis 
and R. keitloa. And, looking to the extent of country between the known patrie of 
these species and the Nubian form to which our animal belongs, I think it by no means 
unlikely that the latter may be ultimately found to belong to a third species, or, at all 
events, to a third well-marked geographical race.

* See also Gray, Ann. N. H. ser. 4, vol. iii. p. 244 (1869), where Mr. Jesse’s specimen, killed in Abyssinia, is 
referred to R. keitloa. But in the same author’s ‘ Handlist,’ published in 1873 (p.51), Mr. Blanford’s specimen 
killed on the same occasion is entered as Rhinaster bicornis! (1. c. p. 51. sp. 1365. k).
