Diagnosis
ReferenceDiagnosis
C. W. Wright et al. 1996Rather evolute; whorl section circular, oval, or subquadrate; early whorls with constrictions and associated ribs; later whorls with strong ribs and 9 to 13 rows of more or less equal tubercles, equidistant or not; ventrolateral and siphonal tubercles may be clavate. On mature whorls some or all tubercles disappearing and ribs mainly long and strong, uninterrupted on venter.
