AFRICAN GAME ANIMALS 
to the square-mouthed species, which is never found east 
of the river, in the domain of the hook-lipped species. It 
is an added singularity in the distribution of these African 
rhinos that in South Africa they should have abounded in 
the same localities, while in the north their ranges are 
sharply divided by the upper Nile. 
Our observations of the square-mouthed rhino were made 
during the three or four weeks we spent at and near our 
camp in the Lado, about midway between Lake Albert 
Nyanza and Nimule. All told we must have seen about 
fifty individuals. Of course we molested none after obtain¬ 
ing the full series needed for the collection; the extreme 
rarity of the species in collections rendered it of much im¬ 
portance that the series should be full. 
We found them rather more gregarious than the common 
kind. Once we found four, and once five, together; in the 
former case they were lying down, so that it was not a mere 
fortuitous gathering to graze. Ordinarily they were found 
singly, or a cow and calf—often two or three years old— 
together; or a bull might be with the cow and calf. They 
are purely grazers, grass-feeders, and live only where there 
are great plains covered with the dry African pasturage; 
but these plains are generally dotted with clumps of bushes, 
and with a scattered growth of scantily leaved thorn-trees, 
acacias. The country is crossed here and there by broad, 
smooth, well-trodden trails, made by the elephants with 
some help from the rhinos, and often travelled by other 
game. We found the rhinos going to water, either at the 
Nile or some pond, during the night. They would then 
feed slowly back into the dry wastes, their spoor through the 
tall grass or over the burnt places being readily followed by
