|---|---|---|
| J. B. Knight 1941 | High-spired, many-whorled, phaneromphalous gastropods, with a selenizone low on the whorl face just above the lower suture; whorl profile moderately arched between sutures; sutures sharply incised but only moderately deep; base rather flatly rounded, phaneromphalous, turning rather sharply into the umbilicus; nucleus unknown; columellar lip not well known, but seemingly straight, only slightly thickened and reflexed about the umbilicus; parietal inductura seemingly thin; outer lip with a shallow, angular, asymmetrical sinus culminating on the lower margin of the whorl face just above the line of the lower suture in a notch or slit of unknown but probably little depth that gives rise to a moderately broad, flat selenizone, the margin of the lip passing down from the upper suture with moderate backward obliquity and gentle forward convexity to the selenizone becoming more strongly oblique close to that feature, below the selenizone passing onto the base and into the umbilicus with rather strong forward obliquity but little forward convexity until close to the umbilicus; selenizone moderately wide, flat, slightly raised above the general surface, with a few, very fine, revolving striae; ornamentation, other than features mentioned, fine lines of growth only; shell thin, its structure unknown. The holotype must have measured about 70 mm. in height before breakage, with width of 26 mm., and a pleural angle of 17 degrees. |
