How to Know the Amphibians and Reptiles

"Our goal in writing this manual was to provide identification keys, descriptions, and distributional notes for amphibians and reptiles of North America, north of Mexico. To our knowledge, it is the first volume to contain identification keys for all species of herpetiles in the US and Canada. Thus, the book should be useful for college level herpetology courses which require students to identify species in any area of the country. While providing the technical details necessary for species identification, we have tried to keep the terminology simple and to give sufficient explanations of terms parenthetically in the text and in the glossary so that interested amateurs and precollege students will also find the book useful."
