Neotropical Rainforest Mammals, the first color-illustrated field guide to these highly diverse and elusive creatures, has enjoyed tremendous success since its initial publication in 1990.

In this completely revised and updated second edition a total of 315 species and genera are covered in individual accounts (includes 24 accounts new to this edition); all species accounts retained from the first edition have been updated; all 195 maps present current information on the distribution and geographic range of each species; and twenty-nine beautiful color plates illustrate more than 220 species (including significant color variants between males and females or adults and young).
