Thanks, Paul!
It's a pretty little shell, even if it is common.
I am still having computer problems, mainly messages that
I supposedly have sent and have not, which were returned
because they were infected (this has happened only on the
alternate e-mail, unfortunately the one to which my images
are automatically routed). So for now, I shall have to
suspend my identification of a few of the bivalves.
When it clears up, I'll send you those images.
Cordially,
Linda
