This and all other snail shells found at this site were found in a mound of flood debris. Thanks to @benhutchins for helping me with all the IDs! For the Pupillids, we used the keys found in Nekola and Coles, 2010, Pupillid land snails of eastern North America. I would not be at all surprised if we have made a few mistakes.

Found in litter sample under oaks. Only a single shell found. This seems to be the closest match I can come up with, but I'm open to other suggestions.
