This book was released on 1923 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The naturalist frequently finds that to learn to identify species is a most difficult task, and yet nothing is more important to his work. He finds that species are not separated merely on shape and colour, but on structural peculiarities which frequently are connected with particular habits. This is especially the case in vertebrate animals, which in Great Britain, with its very limited number of forms, may be identified in a haphazard manner by elimination. This is impossible in a country where different climatic areas interdigitate and where there are many species, as the United States, which for the purpose of the naturalist is a continent. Here Prof. H. S. Pratt ?fills the bill ?by his ?Vertebrate Animals of the United States,? which, however, omits birds. A short account of each group is given, the anatomical features dividing it up into sub-groups and families being usually illustrated. Where neces-sary, special features for families are described and then follow keys to the genera, descriptions of the same and keys to their species. The whole closes with a good bibliography and a glossary of technical terms. The short descriptions of each species, with mention of their geographical distributions and habitats, are excellent, and the tabulation of the sub-species most useful. We learn that there are about 600 species of freshwater fishes, 70 of newts and 61 of frogs and toads we are given a key by which their tadpoles and eggs can be identified-300 reptiles and a wide series of mammals belonging to 9 orders. We characterise this publication as a book for ready reference, such as should be on the shelves of all American naturalists.

Available in PDF, EPUB and Kindle. Book excerpt: The most thorough treatment of lizards of the United States and Canada when first published in 1946, Handbook of Lizards has become a landmark among herpetologists and lizard specialists. Hobart M. Smith spent years compiling and organizing information on 136 species of lizards for this classic study. With more than 300 illustrations, including black-and-white photographs, labeled drawings, range maps, and illustrated keys, this volume serves as a still-relevant and convenient reference guide to the study of North American lizards. Darrel Frost, a prominent lizard specialist, provides a foreword for the 1995 paperback edition that underscores the work's relevance for herpetology today. In the first section, Smith covers in concise fashion the habits, life history, habitats, methods of collection and preservation, and structural features of lizards. The second section of the book considers each species under topics that are conveniently arranged for studying both living lizards and laboratory specimens: range, type, locality, size, color, scalation, recognition characters, habitat and habits, and references. Smith also discusses problems for further study and gives recommendations for special investigations of each species. The book concludes with an extensive bibliography.
