Aegopinella reussi

(Original description in German) The shell is very flat and conical, with an almost flat apex and a moderately flattened, not very wide and continuously umbilical lower end.

It comprises five flatly arched whorls, separated by deep sutures.

The body whorl measures approximately three-quarters of the total shell height.

The obliquely positioned aperture is broadly moon-shaped and features simple, sharp edges.

[2] Fossils of this extinct species were found in late Miocene strata in the Vienna Basin, Austria.
