Diagnosis
ReferenceDiagnosis
J. Gründel and A. Nützel 2012See also kaiM (2004) and kaiM & beisel (2005). The shell is slender to broadly oval. The protoconch is smooth and mostly coaxial or almost coaxial with one to two visible whorls. The teleoconch whorls have a narrow, sometimes indistinct ramp with rounded abaxial edge as transition to the whorl flanks. In a few cases, the ramp is more pronounced. The whorls are ornamented with spiral grooves, which are especially frequent on the base and sometimes only present there. The spiral furrow that demarcates the ramp is pronounced in some species. The growth lines are prosocyrt from the suture to the centre of the base. The aperture is narrow oval with acute adapical portion and broad abapical notch. The outer lip is evenly convex. The inner lip is broadened, forming a ledge which covers an umbilical chink. The columellar lip is straight; the parietal lip is oblique and convex; both enclose a blunt angle.
