ea. vol: 47p. photogs. bibliog. glossary. index. (Discovering Nature Series). Watts. 1987. PLB $10.40. Grade 4-6 Sharp color photographs com plement the texts on almost every page of these three well-organized introduc tions. Each briefly describes its animals' general physical and behavioral charac teristics; methods of locomotion; diet; feeding habits; courtship, mating, egg- laying and other reproductive activities; habitats; natural enemies; and defense mechanisms. The Coldrey and Wharton titles also discuss ways humans threaten the survival of the species. On the whole, the books are succinctly and accurately written; however, they omit some im portant data. All species depicted are only identified by common names, not scientific ones, and while Slugs and Snails identifies the animals' phylum and class, the other two do not. In the Wharton title, important scientific terms, printed in boldface, are defined only in the glossary (sometimes impre cisely), an unnecessary handicap. Other books are available on these subjects, although most do not provide the same broad coverage . Russell's The Crusty Ones: a First Look at Crustaceans (Walck, 1974; o.p.) includes much the same information as the Bailey book; however, it does not discuss as many species and is illustrated with black-and- white drawings. Johnson's Snails (Ler ner, 1982) examines land snails in more detail than the Coldrey title, but does not discuss slugs nor include as much data on marine snails. Little general data on ducks, geese, and swans is available; most books are on individual species. Karey Wehner, San Francisco Public Library
