Ir is strange that a region like the Lower Congo basin, so 
richly forested, should be so poor in monkeys. On the 
river Kwilu, a little to the north, and on the Quanza, to 
the south, the Simiw are abundantly represented, and the 
surrounding conditions of nature are much the same. 
Nevertheless, just as with the snakes, you might journey 
up the Congo from the coast to Bolobo and not see a 
single monkey. The only times I ever came across them 
myself—that is to say, in a wild state—were in the 
uninhabited Inga country, between Vivi and Isangila, in 
which district I have frequently seen a large brown 
Cercopithecus, whose species I could not determine, that 
makes a great unwieldy nest or platform of sticks on the 
higher branches of the trees, and sits on it, watching the 
passer-by. I have also been able to identify the existence _ 
of several well-known West African species by skins — 
worn by the natives, or brought for sale. In this way1 — 
have ascertained the presence of the beautiful Diana 
monkey,* the Pluto,t the grivet,t the sooty mangabey,§ 
and the Colobus.|| It is possible that all West African
