The Neotropical land and freshwater malacofauna gets more and more attention over the past decades. Of several South American countries faunal lists have been published during recent years. This book is the first one dealing with a specific country and presenting an illustrated catalogue of species. It lists 1074 species of which 956 gastropods (89%) and 117 bivalves (11%); 700 (65%) are terrestrial, 373 (35%) are freshwater species. A modest number (33) of exotic species introduced in Brazil is listed in an appendix. The book gives illustrations of nearly all species, mostly from at least two sides. Many type specimens are depicted, for which mostly American and European museums have generously supplied photographs.
