Rough-lined elimia
The rough-lined elimia, scientific name Elimia pilsbryi, was a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Pleuroceridae. This species was endemic to the Coosa River system of Alabama in the United States; it is now presumed extinct, due to the impoundment of the river. References
