---|---|---|
D. Fehse and B. Landau 2002 | Shell very small, inflated; dorsal sulcus weakly developed and not extending across the whole dorsum.
The characteristic features of this genus are the small, globular or subglobular, bulbously inflated shell, the presence of a dorsal sulcus of variable strength, which hardly influences the dorsal ribbing and short blunt terminals. |
