Research in diseases caused by digenetic trematodes requires an adequate knowledge of the snail fauna of the areas where these diseases are endemic. How to distinguish between the transmitting snails and the nontransmitters is also necessary. Dr. Brown's book on the Freshwater Snails of Africa and their Medical Importance is a welcome addition to regional faunal works in Africa during this century, such as Pallary, 1909 (Egypt); Pilsbry and Bequaert, 1927 (Zaire, former Belgian Congo); Connolly, 1939 (South Africa); Mandahl-Barth, 1954 (Uganda); Wright, 1963 (Angola); Wright, 1965 (West Cameroon) and Brown, 1964, 1965) Ethiopia). The book is a vast compendium written in a concise and lucid style by an eminent malacologist who spent most of his career in Africa.
Freshwater Snails of Africa and their Medical Importance, after an Introduction (Chapter 1), begins with a systematic synopsis (Chapters 2, 3 and 4) of the Prosobranchia, and the Basommatophora of the Euthyneura.
