Diagnosis
ReferenceDiagnosis
B. Kensley and J. Pether 1986Protoconch of H smooth whorls; 4 postnatal whorls. Aperture subequal to, or slightly longer than, spire. Sculpture consisting of rounded axial ribs and spiral lirae. Axial ribs: 11-12 on first whorl; 11-12 on second whorl; 11 on third whorl; 11 on body whorl. Spiral lirae: 4 on first whorl; 5 on second whorl; 5 on third whorl; 5 (with 1 or 2 very fine intermediates) on fourth whorl; 18-20 on body whorl (outer lip), including several finer intermediates; lirae running on to anterior canal. Lirae somewhat broadened at intersection with axial ribs, but never becoming bead-like. Narrow, smooth columella callus present. Inner surface of outer lip with 8-10 faint spiral ribs.
