Book excerpt: Lord Howe Island has Australia's highest diversity and endemicity of land snails. These beautiful but vulnerable creatures are not as readily observed or as well understood as the bird or plant life of the island, but play a vital role in the terrestrial ecosystem. For the first time, the native and endemic land snails of Lord Howe Island are shown together in this illustrated guide, designed for anyone from enthusiastic nature lovers to land snail specialists. Features of the guide include a pictorial guide to families and a dichotomous key for easy identification, and detailed descriptions of each genus and species, including distribution maps and photographs of the shell and (where available) the live animal. All descriptive terms are explained and illustrated in the introductory material and in the glossary.
