Extensively revised edition of this complete and concise list of the living and recently extinct species of mammal in the world. Over 4,300 species are now listed; new techniques have meant significant re-evaluation in classification, leading to the addition of 100 species to the list. Each species is given scientific name, English name, and commonly used synonyms. Another change from the second edition is the inclusion of a pen and ink drawing by Ray Burrows for each family.
