Gastropods
Gastropods are a large taxonomic class within the molluscs, a group of animals that are more commonly known as snails and slugs. With more than 30,000 living species world-wide and about 15,000 fossil forms, gastropods have a history as far back as the early Cambrian period. In this book, the authors present current research in the study of the diversity, habitats and genetics of gastropods. Topics discussed include gastropods as paleoenvironmental indicators; diversity in the growth patterns of marine gastropods; the molecular structure of the snail PCTS influencing their habitat; European terrestrial gastropod distribution; and, diversity and gastropodochory studies.
Naturalised Terrestrial Stylommatophora (Mollusca: Gastropoda)
Focusing on naturalized terrestrial gastropods, this is the 38th volume of a series on the fauna of New Zealand. There are 15 species of snail and 14 species of slug in the New Zealand naturalized fauna.

A nomenclator of extant and fossil taxa of the Valvatidae (Gastropoda, Ectobranchia)
The present catalog provides a compilation of all supra- and (infra-) specific taxa of extant and fossil Valvatidae (Ectobranchia), a group of freshwater operculate snails (Gastropoda, Heterobranchia). Taxa initially described in this family and bsequently classified in other families (in particular Hydrobiidae and Planorbidae, but among others also larval shells of trichopteran insects) as well as names due to errors or misspellings are likewise included. For each taxon the full original reference and the ype locality (and type horizon in fossils) is provided. Remarks on nomenclatorical problems and possible solutions are added if necessary. As a novelty the extensive reference list is as far as possible directly linked to the internet source (digital view or pdf-download) of the respective papers to facilitate future taxonomic research.
