Rowell’s Cochliopa Snail (Cochliopa rowelli)  

Rowell’s Cochliopa Snail, which was described in 1863, appears to have always been restricted to its type locality, the Río Matasnillo in Panamá City, Panama.  

The species is now considered extinct, possibly caused by the pollution of its habitat. [1]
