The rainforests in the southwestern part of the Amazon Basin in southeastern Peru are home to scores of amphibians and reptiles. Cusco Amazonico is a richly illustrated and comprehensive account of the lives of 151 of these species. William E. Duellmans masterpiece of community ecology includes descriptions of the physical environment and vegetation found in this unique habitat along with syntheses of abundance, mass, feeding, reproductive guilds, and daily and seasonal patterns of activity. Identification keys in English and Spanish precede detailed and illustrated species accounts. Tadpoles of many frogs are described and illustrated.

Cusco Amazonico will become a standard reference for herpetologists, tropical biologists, biogeographers, ecologists, and conservationists and stands on its own as a portrait of an animal community in a unique bioregion. The illustrations include 236 color photographs, 121 charts and graphs, 16 maps, 42 line drawings, 2 halftones, and 56 sets of audiospectrograms and waveforms. There are 71 tables.
