The family Bulimulidae is a dominant land snail family in the Neotropics, with more than 1000 nominal taxa described. Revisionary work has only partially been done, but many genera need further revisionary work for which a sound taxonomic basis is needed. Type specimens for more than 400 taxa of this family are present in the Natural History Museum, London, U.K., and are documented in this paper. For each taxon the relevant literature is cited, type locality, label, the provenance of the specimens, and the current systematic position; photographs of nearly all type specimens and labels are also provided.

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.
