Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. Alf 2019 | Shell small to medium in size, sturdy with dome-like spire or coniform; periphery sharply angulate or rounded; sculpture smooth, spiral, or rugose. Umbilicus open in juvenile shells, opened in mature specimens or covered with callus, leaving broad umbilical depression. Columellar wall arched, columella with denticles, largest one at termination of spiral cord bordering or passing into umbilical cavity; aperture oblique, sometimes with lirations inside, interior nacreous, white or brightly colored. Operculum uncalcified. Color always dark, usually gray, black, or brown. |
