The spiral sculpture also consists of (on the last whorl about 25) obliquely retractive low folds which barely reach the periphery, with narrower interspaces, but are feebly and irregularly revived on the base, especially near the umbilicus. The subcircular aperture is hardly interrupted by the body and has a sharp thin margin.
