Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. D. d'Orbigny 1839 | Shell free, spiral, elongated, rough. Conical coil, very elongated. Depressed lodges, stacked in three distinct lines, each streamlined around the longitudinal axis. Transverse slit opening located on the internal part of the last pocket and without an opercula valve. Relationships and differences. The external form of this genus is analogous to that of the elongated and triangular valvulins; its spiral bearing is the same, but the opening, instead of being protected by an opercular valve, is simple, formed only of a transverse slit, under the inner edge of the last cell, as is seen in Textiles in the Enallostegues. Until now, we only know the white chalk of the surroundings of Paris. |
