Please send all Cornish records of marine molluscs, with images if possible, to David Fenwick. I will make sure records are collated and passed on to the national recorder at the Conchological Society of Britain and Ireland. I will also hold a set of records for use by other Cornish conchologists, researchers, and the Marine Biological Association.
