The specimens examined consist of the series collected 
by the Smithsonian African expedition under the direction 
of Colonel Roosevelt at Rhino Camp, Lado Enclave. The 
precise geographical position of this spot is latitude 2 0 55' 
north, on the west bank of the Nile, some fifteen miles north 
of the station of Wadelai. This material consists of four¬ 
teen specimens: the complete skins and skeletons of two 
adult males, two adult females, one calf, and one mature 
foetus; the head skins and skulls of three adult females; 
the skull of a male, and four weathered skulls found on 
the veldt, two of which are undoubted males and two 
females. Besides this material in the National Museum 
the writers have examined specimens from South Africa 
in the British, Paris, and Hamburg Museums as well as 
Nile specimens in the Congo Museum at Brussels, and a 
large series in the private museum of Major Powell-Cotton 
at Quex Park, England.
