A remarkable achievement that took over 30 years to construct, Keys for Identifying Mexican Mammals is the only complete identification guide to Mexico's mammalian fauna. Fully updated and revised, this bestselling book follows a bilingual arrangement, with identical information presented in Spanish and English on facing pages. The dichotomous presentation is both easy to follow and flawlessly compiled, including updated and expanded material that surpasses any previously available resource. Hundreds of diagnostic images are dispersed throughout the book, many showing minute details that differentiate one species from another, and introductory materials carefully explain the use of diagnostic features. The heart of the book, though, is the keys themselves, which cover every taxa-from artiodactyls and carnivores to primates and rodents-while allowing confident identification at the species level for both field and museum use. The book closes with appendices that cover preparation of specimens, a glossary, and a bibliography. Anyone with an interest in the mammalian fauna of Mexico, or mammals in general, will find this one-of-a-kind book an indispensable reference to Mexico's rich diversity of wildlife.
