The lack of an authoritative guide to the identification of the snail intermediate hosts has impeded work on schistosomiasis in the Americas. This new Guide is an expanded and improved version of a mimeographed report that was circulated informally in 1965. The authors, all specialists in medical malacology, provide a concise, accurate, and up-to-date account of the ecology, morphology, nomenclature, and identification of the Neotropical species of Biomphalaria. A series of well-executed line drawings supplement and amplify the text. The Guide also contains a glossary of malacological terms, a bibliography of more than 150 references, and some overly brief outlines of techniques used in collecting, maintaining, and studying these snails. An excellent “Key to Neotropical Biomphalaria Species” is provided. The Guide represents a major contribution to the practical aspects of medical malacology in this hemisphere. A companion volume treating the African Biomphalaria would be most welcome.
