Hi:

I've just joined the list.  I'm British; have collected British and
Mediterranean shells for many years on-and-off.  I may be able to help
with British enquiries and material; my knowledge of Med shells is much
patchier.

Most of my collecting is of dead shells from beaches, including
micro-shells;  I don't hold with live-collecting except of things that
are clearly common where collected.
