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.
|R. L. Squires and L. R. Saul 2007||Small to large (up to approximately 95 mm shell height), turritelliform, slender to conical rotund. Pleural angle ranges from 15° to 41°. Protoconch conical, small, smooth, and approximately two whorls. Protoconch to teleoconch transition gradual. Teleoconch whorls up to 16, whorl sides convex to flattish/concave. Sculpture on early juvenile teleoconch whorls variable, ranging from nearly smooth or with very fine, unicostate, whorls highly variable, ranging from smooth to numerous, weak to moderately strong closely spaced spiral ribs, but less commonly with fewer and more prominent spiral ribs. Growth lines parasigmoidal on last whorl (including base); lateral sinus variable in amount of concavity (flexure). Aperture with shallow effuse spout, ranging from somewhat constrained to broad. Adapical edge of spout usually forms weak spiral ridge that continues onto columella.|
