Dear Mark,
I'm back on Conch-L for a little while.
As far as I am concerned the two shells, C. floridanus and C. burryae
are not different species. I used to find both of them at Harry Harris
Park, Tavernier Key and examples between to two. The Johnsonia 1, No. 6
has the description of the types and compares it to C. floridanus
floridensis.
I used to think the subspecies C. floridanus floridensis was actually
a valid species. Until I saw some specimens from the lower Florida Keys
that looked like hybrids between the C. floridanus and C. floridensis.
I suppose any area may potentially yield shells which have relatively
minor differences compared to similar representatives in adjacent or
nearby areas. This seems to be phenomenon of certain Cones and some
other Molluskan species.
I think its interesting that some other Genera such as Turridae, do
not vary much from place to place.
