|---|---|---|
| J. B. Knight 1941 (Aulopea nelsoni) | Moderately large, irregularly subglobular, narrowly phaneromphalous gastropods with sides of whorls flattened and the outer lip extending broadly forward between an upper and lower notchlike sinus; whorl profile broadly and roundly shouldered above, flattened or slightly concave on the sides; sutures deep; nucleus unknown; base rather narrow, somewhat extended, narrowly phaneromphalous; columellar lip somewhat irregular, reflexed about the umbilicus; parietal contact rather narrow, inductura thin; outer lip with a shallow sinus on the crest of the shoulder close to the upper suture, a broad forward extension on the sides and a second sinus on the narrow base, the latter sinus being rather deep and notchlike; ornamentation rather coarse lines of growth only; shell thin, its structure unknown. The holotype measures 26.5 mm. in height, 29.5 mm. in width, and has a pleural angle of about 121 degrees. |
