The most comprehensive one-volume guide to worldwide seashells ever published, this lavishly illustrated book (158 full-colour plates) includes nearly 4000 specimens, representing over 2600 species carefully selected for their colour, pattern and perfection. All of the species included were chosen for their beauty, exotic nature or popularity. In addition, many unusual and obscure shells have been shown to represent families that are usually missing from most guides. All species are listed with their scientific and popular names, geographical distribution, range of sizes, forms, rarity and valuation. In the index all known species of the most popular groups such as cowries, cones, murex, olives and volutes are listed and evaluated. The characteristics of 142 seashell families are described in detail, with an accompanying illustrated identification guide. Nearly all of the shells are illustrated in 2/3 to full scale. The specimens on each full plate are all shown in the same scale. Each major gastropod family is illustrated on a different colour background. The introduction covers classification, nomenclature, form, life habits, geographical distribution, and suggestions for the beginning collector. A special chapter is devoted to a systematic listing of all known seashell families. Also included are a glossary, annotated bibliography, and a worldwide listing of the principal shell clubs and museum collections. This book is a "must" for every reference library.
