Analysis of Collections | Mollusca Types in Great Britain

Scope of the database

The website is intended as a unified catalogue of Mollusca type material held at the participating museums. It aims to include records for all primary name-bearing types (holotypes, lectotypes, syntypes and neotypes). We have researched and verified their status as best as we can, and the great majority have also been photographed, along with their original labels.

Despite our attempts to be comprehensive, it is likely that additional type material remains unrecognised in some collections. Coverage of non-primary types (paratypes and paralectotypes) is much less complete, and varies across museums. However, we have included some of these, and even some non-type material, where they were dealt with as part of the project. In the absence of types, some material may be suitable for future neotype designation.

Eight UK museums currently have material in the database. The type collections at the Natural History Museum, London, are orders of magnitude larger than those at any of these. Access to the Mollusca types in the London collections is therefore provided via a customised link to their Data Portal.
