Just a short thank you to all of those who so promptly replied to my query about fossil classifications; I now know where to look.
That is one of the good things about Conch-L - the rapid response to queries.
My sincere apologies for giving the wrong author to "Classification of the Living Mollusca"; that shows one of the problems of putting together a message, however short, late on a Sunday night!
