FORMER AND PRESENT RANGES OF THE TWO WHITE RHINOCEROS SUBSPECIES

the hopeful omen of the presence of black 
rhinoceroses in the Niger-Shari districts, south 
of Lake Chad, especially as both species were 
found together in many regions of South Africa. 
According to the information of Maruka, an 
intelligent native chief of the Logo at Faradje, 
it may be possible that in former times the two 
kinds of rhinoceroses shared their ranges in the 
northeastern Uele. He told us that when the 
rinderpest swept across Africa from the north- 
east in the early nineties, the rhinoceros feed- 
ing on bushes died out, together with most of 
the buffaloes, elands and antelopes, and never 
appeared again. Only in the last ten years have 
the white rhinoceroses and other game become 
sufficiently numerous in that section to figure 
once more in the natives’ larder.

positive proof of their former 
occurrence there has come to light, notwith- 
standing various reports to the contrary. In 
regions where hyenas abound and long rainy 
seasons accelerate the destruction of even the 
heaviest bones, the chances are slight that their 
remains have found a safe burial, to come to 
light again as witness to former flourishing 
times. In ages past Africa has changed, though 
less and more gradually than other continents, 
and instead of whole mammal groups being com- 
pletely wiped out. some were able to hold their 
own in scattered areas. Interrupted distribution
