 slightly smaller tlian the male, but the great disparity observable 

 in the Gorilla does not characterise its ally. The animal, like

 forest-clad region of the equatorial belt is their home.

 panzees is to be found in a work upon the Kingdom of Congo, 

 published in 1598. In a cut illustrating that work, and of
