I've been following the discussion with amusement and much appreciate the
true confessions of Paul Monfils and Ferreter. I got a call several years
ago from a woman whose only shelling experience was at Sanibel. What she
called about was a shell she could not identify. It took no time at all to
realize she had a Lambis species. She was certain she had found it on the
beach just off the hotel at Sanibel. I told her no way was it native and
she was a bit disappointed.
