Olivier Gargominy of the Muséum national d'Histoire naturelle in Paris has asked me to place this request in Mollusc World for records of nonmarine molluscs from France.

In the guide to the Freshwater Bivalves of Britain & Ireland (Killeen, Aldridge & Oliver 2004) we recognised Sphaerium nucleus (Studer, 1820) as part of the fauna.

I recently had to identify some Oxychilus from South Wales, a job made considerably easier thanks to the work of Mr. J. Davy Dean (1876-1937).
