Excerpt from An Annotated Checklist and Key to the Amphibia of MexicoIn preparing this summary we have followed, with some exceptions, the style of our Annotated Checklist and Key to the Snakes of Mexico. 2 The present account differs chie¿y in the natural arrange ment of the species and in the distribution of the keys, Which instead of being united are scattered through the list in appropriate places. The keys are to transformed specimens, except where otherwise indicated, since the larvae are too incompletely known to permit the construction of useful keys. Likewise the eggs of relatively few forms are known. Juvenile transformed specimens will not be identifiable in all cases, since important characters may not be evident in them.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
