). It allows the study of the adult conch as well as portions of the inner whorls. Its last volution is extremely discoidal and subevolute. It is widest at the rounded umbilical margin, from where the flanks strongly converge towards the tectiform venter. This shape of the venter is developed only during the last half volution; the venter is still rounded at 180 degrees before the largest diameter. The ventrolateral shoulder bears two longitudinal grooves on each side. The inner whorls are very evolute and it appears that the whorl profile is crescent-shaped throughout most of the ontogeny.

). It has an extremely discoidal and subevolute conch; the whorl profile is compressed with shallow umbilical wall, rounded umbilical margin, and convergent flanks that are widest at some distance from the umbilicus. The venter is narrowly rounded in the penultimate whorl, but developing into a subacute shape with a rounded keel at the end of the last volution. The inner whorls display coarse growth lines which become finer on the last volution. Runzelschicht is present in the dorsal whorl zone; it consists of fine wrinkles with slightly prorsiradiate direction.

The narrowly rounded venter is separated from the flanks by a subangular margin accompanied by a shallow spiral groove. In the penultimate whorl, the venter develops into a subacute shape with a rounded keel at the end of the last volution. The inner whorls show a rather well-preserved ornament; the growth lines are coarse in the inner whorls and slightly finer on the last volution.

A clear separation using conch characters in small specimens may be difficult, but the compressed whorl profile and the rather narrow venter may serve as good criteria.
