Hi Winston,

I've seen the same combinations you indicated, but prefer to just consider
the unique Lake Worth colony "hybrids."  See photos and discussion:

We did indeed take samples of these shells and their DNA analysis will be
added to the data base.  However, at this time Dr. Paulay's Florida
initiative is devoted to data collection and data base development.
Comparative analysis will await the initiative of others more specifically
investigating Strombs.  Click this link to read more about the Florida

Dear Winston,

I think there are enough names already.

Perhaps we'll learn something of the intergradation of these two
morphospecies with the genetic barcoding initiative of Dr. Gustav Paulay and
his collaborators at the Florida Museum of Natural History and elsewhere. I
think they may have obtained tissue of each taxon in March, 2008 during an
expedition to Peanut Is. Conch-L'er Marlo Krisberg was a member of the
party; perhaps he recalls.

For now, I think it is fine to simply consider Peanut Is. the metropolis of
hybridization between the Carolinian S. alatus and Caribbean S. pugilis as
we currently understand those two species.

Some questions arise after viewing the Peanut Island list:
Is there an accepted name applied to Strombus alatus with introgression of
S. pugilis?
I have seen S.pugilis /alatus and S. alatus /pugilis , but never S
alatus x pugilis 
Is this an appropriate example of the term clinal form ?
If it is considered a form, does it have a name?
