One of the best animal reference books I have ever come across, and in a handy size to boot! Filled with detailed write up on each species including description, evolutionary history, habits and behaviors etc. Illustrated throughout with beautiful hand drawn and painted examples of the animals, no less by the author himself, evidently a talented artist as well as naturalist! The sheer diversity of mammals on this continent boggles the mind, particularly of primates and antelope. Though this work is encyclopedic in its treatment of species, while there are brief discussions on genealogy and origins, it is by no means a full fledged treatise on evolution. However it does what it sets out to do - be a comprehensive field guide, with flying colors.
