The following new vice-county records have been confirmed since the last Report (J. Conch. 38: 722-724, 2005). Unless stated otherwise all were confirmed from specimens collected during 2005. The report is a collation of new verified records received by the Society's Non-marine Recorder, not a review of the published literature. Roy Anderson (2005) published a new list of the non-marine Mollusca of Britain and Ireland (J. Conch. 38: 607-638). This provides a welcome update of taxonomy and nomenclature that is followed here.

There were two additional records which are particularly noteworthy. John Harper recorded Peringia ulvae from the Severn Estuary, Magor in Monmouthshire (vc35) which is only the second record of this species in the county and it updated the original and unlocalised vice county record dating from before 1900. Barry Colville found several live adults of Truncatellina cylindrica at Horden in County Durham (vc66) which was otherwise known in that county from an 1848 record from Claxheugh nr Sunderland.
