Conchological Society of Great Britain & Ireland: non-marine molluscs (rare and scarce species)

The records in this dataset are the results of a compilation of records of rare and scarce species within Great Britain and Nothern Ireland. It was assembled and maintained by Michael Kerney on behalf of the Conchological Society and was subsequently digitised. The exact source of digitisation is unclear and the quality of the data are still being verified by the Society. All the survey data were collected by members of the Conchological Society. Recording is still continuing but records are added to a separate dataset.
