A Field Guide to Reptiles and Amphibians: This newly designed field guide features detailed descriptions of 595 species ad subspecies. The 656 full-color illustrations and 384 drawings show key details for accurate identification. More than 100 color photographs and 333 color distribution maps accompany the species descriptions. Roger Tory Peterson's unique system shows exactly what features to look for to tell one species from another. For each Field Guide, an author with expertise in the subject and an experienced artist work closely with the editors to ensure that both text and illustrations are accurate.
