Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. L. Batten 1995 | Trochiform to turbiniform shells with sharply developed nodose ornament. Early whorls smooth, spiral ornament appears at third whorl. Upper whorl surface flattened with fine spiral lirae at fourth whorl, with fine spiral lirae developed on outer whorl surface. Sutures deeply recessed. Adult whorl upper whorl surface evenly rounded with two or three spiral cords forming sharp nodes with collabral ornament. Outer whorl face evenly rounded to flattened and moderately wide to narrow. Selenizone margins are rounded spiral lirae. Lunulae form interference nodes with medial spiral thread. Upper selenizone margin marks shell periphery. Selenizone slopes downward and inward. A spiral cord just under selenizone forms strongly developed nodes with collabral ornament. Flatly rounded base has five or more spiral cords which may have intercalated threads. Anomphalus or narrowly phaneromphalus. Aperture unknown. |
