This classic work, originally published in 1919-1923 in three volumes, is the most comprehensive work on the herpetology of Central Africa and still an essential reference for the Congo rain forest and the Sudanese savanna. Covers a total of 133 species of reptiles and 56 species of amphibians. The extensive new introductions by Donald Broadley and John Poynton, who are acknowledged authorities on the herpetofauna of sub-Saharan Africa, include the current nomenclature for Schmidt's and Noble's names, biogeographic analyses, and bibliographies of Congo herpetology to update those in the original books.
