---|---|---|
R. L. Batten 1972 | Turbiniform to trochiform shells with a narrow selenizone; wide to narrow depression adjacent to suture; dominant spiral ornament; shell shape variable; early whorls smooth, flattened to gently convexo-concave; shell shape dependent, in part, by relative width of flat to concave area adjacent to suture and in part by the relative convexity of whorl; selenizone narrow, faintly to moderately strongly bordered; sutures embrace whorls slightly below lower selenizone margin; ornament dominantly spiral cords, collabral ornament subdued except for interference nodes; nodes common at ornament intersections, more strongly developed near suture and next to umbilicus; hemiomphalus to cryptomphalus; reflexed columellar lip with funicle or callus. |
