Having (fairly recently) re-approached the gastropod book with a view to updating the systematics and taxonomy, I have taken the opportunity also to make a new start on its sister book on bivalves.

Since the above entailed reviewing the species checklist, I have made checklists of the other molluscan classes for Britain and northwest Europe: Monoplacophora, Aplacophora, Polyplacophora (or Amphineura; chitons), Scaphopoda (tusk-shells), Cephalopoda.

Another group, the Brachiopoda, while not molluscs, are in the same superphylum, Lophophorata – and the list for the group is now completed.

Lophophorata Systematics:

A Field Guide to the Marine Gastropods …

As well as my Cleethorpes book (see separate post), I have been preparing a book entitled, ‘A Field Guide to the Marine Gastropods of Britain and northwest Europe’.

The Field Guide describes over 800 species (from northern France to the North Pole) in detail, as well as their habits, habitats, ranges and European distributions.

The book was originally intended as a sister-guide to Kerney and Cameron’s ‘Land Snails of Britain and northwest Europe (Collins) – but, again, I have been unable to find a publisher.

As with the Cleethorpes book, I shall keep trying…
