This 34 page guide offers a brief introduction to amphibians and reptiles whose ranges extend into the northeastern US state of Massachusetts. It chiefly consists of brief descriptions for each of the species with regard to overall appearance, natural history, and geographic distribution. Gray-scale photographs accompany most of the descriptions. A taxonomic key to the species and a glossary of terms is also provided. The taxonomy reflects the 1974 publication date (thus water snakes that have been known as Nerodia since 1977 are termed "Natrix"). It occasionally reflects the author's idiosyncratic views on phylogenetic relationships -- for example, he sees no generic level distinction to be made between water snakes and garter snakes (a view that is not supported by recent molecular evidence).

The book has its utility as well as a certain charm, as shown in the authors descriptions and in his cautionary advice on trying to keep species in captivity. The author's strong professional commitment to conservation is evident throughout. Sadly, of 51 species documented as of 1974, one (the only lizard) was already extinct, 10 species were in danger of extirpation, and 10 others were diminishing dramatically in range and numbers. Four decades later, the numbers are even more grim.

Other guides to reptiles and amphibians are now readily available, including those with distribution maps and color illustrations. However, this work has had its place, in time and space. ( )
