The Simiidse, or Anthropoid Apes, comprehend those forms of 
the monkey-tribe which, in general organization, approach nearest 
to man. They inhabit the tropics of the Old World, and are 
most abundant near the equator ; but they are limited to certain 
districts, being quite unknown in eastern and southern Africa, 
and the whole peninsula of Hindostan. 
The genus Troglodytes (or Minutes , as it is sometimes named) 
comprehends the chimpanzee and gorilla. It is confined to the 
West African sub-region, being found on the coast about 12° 
North and South of the equator, from* the Gambia to Benguela, and 
as far inland as the great equatorial forests extend. There are 
perhaps other species of chimpanzee ; since Livingstone met with 
what he supposed to be a new species in the forest region west 
of Lake Tanganyika, while Dr. Schweinfurth found one in the 
country beyond the western watershed of the Nile. The gorilla 
is confined within narrower limits on and near the equator.
