Book Description
In this definitive work, Ernest Glen Wever establishes the evolutionary importance of the reptile ear as the origin of the higher type of auditory apparatus shared by man and the mammals. Tracing the development of the auditory receptor in the living reptiles, he examines the use of a variety of mechanisms and principles of action by that receptor. While some of the material in this book has appeared previously in journal articles, most of it is presented here for the first time. Basing this study on his twenty years of research at Princeton's Auditory Research Laboratories, Professor Wever treats in anatomical and functional detail the auditory mechanism in about 250 species and subspecies of reptiles. The anatomical treatment rests on dissections and histological examinations of the ears in serial section, and portrays the relevant features in drawings that represent particular views of reconstructions. The author evaluates the performance of thesse ears electrophysiologically, in terms of the electrical potentials of the cochlea, paying particular attention to problems of the transmission of vibrations inward to the cochlea and the actions there in stimulating the sensory cells. Professor Wever finds that the cochlea emerged independently from the non-auditory labyrinth in three different vertebrate groups: fishes, amphibians, and reptiles. It was among the reptiles, however, that the vertebrate ear took on a more advanced configuration from which it further evolved along separate lineages in the birds and mammals. Ernest Glen Wever is Eugene Higgins Professor of Psychology Emeritus at Princeton University. Originally published in 1978. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
Reptiles and Amphibians of Australia is a complete guide to Australia’s rich and varied herpetofauna, including frogs, crocodiles, turtles, tortoises, lizards and snakes. For each of the 1218 species there is a description of its appearance, distribution and habits. These descriptions are also accompanied by distribution maps and, in many cases, one of the book's more than 1000 colour photographs of living animals. The book also includes 130 simple-to-use dichotomous keys, accompanied by hundreds of explanatory drawings, that in most cases allow a specimen in hand to be identified. In addition, it has a comprehensive list of scientific references for those wishing to conduct more in-depth research, an extensive glossary, and basic guides to the collection, preservation and captive care of specimens. This classic work was originally published in 1975. The updated seventh edition contains a new Appendix that discusses recent changes and lists over 80 new or resurrected species and genera that have been added to the Australian frog and reptile fauna since the 2014 edition.
