Published in five parts between 1839 and 1843, and reissued here in three volumes, this work showcases the zoological specimens and fossils collected during Charles Darwin's momentous voyage of discovery. Acting as the overall editor, Darwin (1809-82) enlisted a group of naturalists to assist with the task of identifying and describing the species. Each man contributed a particular section according to his expertise. Volume 3 comprises Part 4 (1842) and Part 5 (1843). Leonard Jenyns (1800-93), who was the original choice as naturalist for the Beagle voyage, classified the fish for Part 4. Over half of these were newly discovered species. Professor of zoology at King's College London, Thomas Bell (1792-1880) classified and commented on the reptiles for Part 5. He also wrote about the amphibians Darwin had collected. This volume contains nearly fifty plates of detailed illustrations.
