Geeze, miss a few days, and the messages just pile up. Topics come and go.
I just want to add that I found a Busycon canaliculatum several years ago
at Cape Henlopen, Del. with a double operc. At the time I thought it
absolutely unique. Very interested to hear of other cases. This list is
sometimes aggravating, but even for lurkers like me, it is interesting and
often informative. Well worth it.
