Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. D. Longstaff 1924 | Shell rather large, turreted. Whorls about five, angular above the middle of the body-whorl, and below in the whorls of the spire, excavated above, almost vertical below; a strong ridge exists between the upper suture and the angle, and another ridge between it and the lower suture. Band on the angle prominent, composed of a thick central keel, with a finer one on each side. Lines of growth coarse, curving back to the band above and forward below with a moderate degree of obliquity, crossed and reticulated on the base by strong spiral threads. Base convex, somewhat produced. Aperture imperfectly known. |
