Pupa Elimia Snail (Elimia pupaeformis)  

This species was described in 1864.  

The Pupa Elimia Snail was restricted to a section of the Coosa River, from about Elmore – to St. Clair County, Alabama.  

The species disappeared after the impoundment of the river due to the building of dams and is now considered extinct.
