Mollusc (marine) data for Great Britain and Ireland - restricted access

The records in this dataset are the results of the Conchological Society's Marine Census which has been run since 1876 where the recorder has not yet signed the Society's access policy. This can occur because the individual is unhappy with the access position or simply because the Society has as yet been unable to contact them. Please note that the majority of the records held by the society are held in a separate dataset with no access restrictions.
