Dear Aydin,
   The snail you found on Chincoteague Island has been identified by David
Robinson as Cernuella cisalpina. It is indeed a European introduction. Clem
Counts says he has known about it on Chincoteague for many years. As far as
I know it hasn't spread from Chincoteague, but I don't think anyone knows
how dangerous of an alien it actually could be.
   I imagine you had a wonderful time on Chincoteague.
   Cheers,   -Tim-

Greetings,
I just returned from a 5-day vacation in Chincoteague, VA, where among
others I collected numerous specimens of a land snail that was almost
certainly introduced from Europe. More details, including photos are at:

I will appreciate your help to identify this snail.
