Diagnosis
ReferenceDiagnosis
J. W. Durham 1937Shell more or less heavy, small to medium size; axial ribs usually nearly obsolete; spiral ribs present; basal disk present; aperture entire although inner lin is often very thin; outer lip sharpened.
R. L. Squires and L. R. Saul 2003Shell acuminate, whorls joined (with only a moderately impressed suture), and not umbilicate. Sculpture much reduced, may be spiral or axial or both; incised spiral grooves usually present. Basal keel absent. Basal disk indistinct but may be defined by a subperipheral ridge (Clench & Turner, 1950; DuShane, 1974, 1979; Kilburn, 1985; Bouchet & Waren, 1986; Dockery, 1993; Neville, 2001).
