Excerpt

This Manual has been written to furnish students of Zoology, students of the Geographical Distribution of animals, and Nature students, with diagnostic descriptions of the land and fresh water vertebrate animals of the United States, together with analytical keys by means of which they can be readily identified and their affinities determined. Many excellent hand-books for the identification of birds already exist, and their number is constantly being added to, and it is for this reason that this large Class has not been included in the present book. There is, however, a very real need of a general modern manual of the fishes, amphibians, reptiles and mammals of the country which shall give the accepted scientific names of species, as well as of the larger groups to which they belong, and also reflect the recent advances in our knowledge of their systematic and structural relationships, their manner of life and their geographical distribution.

The region covered by this work is the whole of the United States between the Canadian and Mexican borders, neither Alaska nor the West Indian or Hawaiian Islands being included; the southern portion of Canada, however, is included, as it belongs to the same geographical region as the northern portion of the United States. With certain exceptions, all the species, as well as the geographic subspecies, of the four Classes of vertebrates above mentioned which are found in this large region, are described, the exceptions being those species which are of doubtful validity, those which are very rare, and certain Mexican species, chiefly of reptiles, which have been observed but a few times north of the boundary. Great care has been taken to state precisely the geographic limits of these species and subspecies.

In compiling this work the author has utilized every source of information at his command, and is consequently under obligations to very many persons; to all of these he extends his heartiest thanks. The section on Fishes is based upon Jordan and Evermann "Fishes of North and Middle America," and one of the authors of this fundamental work, Dr. Barton Warren Evermann, Director of the Museum of the California Academy of Sciences, San Francisco, has read this portion of the manuscript critically. Large use has also been made of "American Food and Game Fishes" by the same authors, and of Jordan
