I need help in identifying this Tree snail found on a concrete pillar located on a fresh water canal Holly Hill, Florida Volusia County.

This appears to be in the Family Bulimulidae, probably a species of Drymaeus.  At first I was thinking Drymaeus dormani, a common Florida species, but it doesn't look quite right for that species.  It really looks more like Drymaeus interpunctus, which however is a South American species. Perhaps an introduced specimen?

Thank you very much for your help Paul. It sure does look like Drymaeus interpunctus. Do you think it could have escaped from a nursery? Perhaps it was on a plant imported from Paraguay. Very interesting website on Paraguay Tree snails by the way.
