If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|J. B. Knight 1941||Rather large, discoidal gastropods, without sinus or slit and with a calcareous operculum; sutures deep, above and below; whorl profile subcircular; spire slightly elevated, and trochiform for the first three or four (nepionic and neanic) whorls, concave and similar to the base at all later stages; base widely and shallowly phaneromphalous; aperture circular, the columellar lip slightly thickened; a parietal inductura present at the narrow zone of contact of the whorls; outer lip without any sinuosities; operculum heavy, calcareous, marked by numerous strong, rounded costae with narrow Y-shaped interspaces, the costae being either concentric or spiral, it is impossible to tell which; ornamentation a series of narrow, low, rounded, revolving costae with wide, flat interspaces and obscure, irregularly spaced growth lines; shell distinctly double-layered. The holotype measures about 43 mm. in diameter, its height being only the greatest diameter of the final whorl, about 18 mm.|
