Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. W. Lauridsen and K. I. Schnetler 2014 | A Zaclys? with a protoconch consisting of c. five whorls with axial ribs and no spirals on the last whorl. The teleoconch has c. 12 axial ribs. The shell is slender and turriculate with a height/width ratio of c. 3.0. The protoconch has six convex whorls, separated by a distinct suture. The first three whorls are smooth and the two terminal whorls have a spiral keel under the middle of the whorl and axial ribs at the adapical suture. The transition into the teleoconch is sharp. The teleoconch whorls are convex and separated by a distinct suture. The spiral ornament consists of four spirals, of which the adapical is weak and situated under the adapical suture. The abapical spiral is weak and situated above the abapical suture and partly covered by the following whorl. The two medium spirals are of almost equal strength and run across 12 axial ribs on each whorl. The knobs on the two spirals are rather weak. The base is smooth. The aperture is rounded rectangular and the canal is short. |
