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.
