Shell description
These small snails are quite distinctive, because they have shells that are sinistral, which means that if you hold the shell such that the spire is pointing up, then the aperture is on the left-hand side.
The shells of Aplexa species have a long and large aperture, a relatively high and pointed spire, and no operculum. The shells are thin and corneous and rather transparent.
