Reptiles and Amphibians of Minnesota was first published in 1944.Both amateur and professional naturalists will find this a useful and authoritative handbook for the study of reptiles and amphibians in Minnesota and the surrounding regions. Dr. Breckenridge was for many years the director of the Minnesota Museum of Natural History and familiar with the needs and interests of those studying the wildlife of the area. In this book he provides a comprehensive yet clearly and simply written text, illustrated with excellent photographs, drawings, and maps.As an introduction to his subject, Dr. Breckenridge tells something of the history of Minnesota herpetology and recounts some of the takes and folklore about snakes, lizards, turtles, frogs, toads, and salamanders. He then describes the distribution of species in Minnesota and outlines methods of field study. He tells how to preserve specimens, how to care for reptiles or amphibians in captivity, and what to do to avoid or treat snake bites.Preceding the detailed descriptions of the species, there is an explanation, especially helpful to the beginner, of the general scientific method of classification and the use of keys. Keys for use in identifying specimens likely to be found in the region are provided.The descriptions themselves include data on the range, habits, habitat, food, and breeding of 45 different species. Most of these species are illustrated with photographs or drawings, and there are a number of drawings that show structural details. Maps show the range of each species booth in Minnesota and on the North American continent. A glossary explains the meaning of terms used in the keys and descriptions.
