Based upon the response I received G. cerina does occur in the Gulf of
Mexico, but it sounds like it's a deep water shell and not found in bays and
estuaries as on Florida's south east coast.  The below presentation has been
annotated and I thank those who provided collecting data.

I've done a workup on this shell, which supposedly is found on both sides of
Florida.  However, I found only one 1969 record for the west coast
(Sanibel).  I'd like to hear from those with first-hand collecting
experience on Florida's west coast.
