Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G.P. Wahlman 1992 | Shell large (up to 45.6 mm long), loosely coiled, with large, open umbilicus; submature whorls subreniform, adult aperture greatly expanded anteriorly with elongate subtriangular outline.
Shell large, consisting of about three volutions, loosely coiled so as to create a wide, open umbilicus. Submature whorls rather narrow and depressed, subreniform in outline; dorsum gently convex, convexity gradually increases at greater rate than width, but in adulthood aperture expands anteriorly at even a greater rate, resulting in an elongate sUbtriangular outline. Posterolateral lip of adult aperture slightly retlexed; anterior lip curved upward into fairly deep V -shaped sinus; parietal lip apparently thickened centrally. Dorsomedian ridge over expanded portion of whorl on internal molds retlects an elevated, hollow slitband. No surface markings known. |
