Material.

13 specimens and fragments, illustrated specimen SNSB-BSPG 2016 XXI 1928 .

Description.

Shell broadly egg-shaped with last whorl much higher than spire; illustrated specimen 67 mm high; apex concave; spire whorl much wider that high; suture emphasized by very narrow ramp; whorl face feebly convex to almost straight; transition from whorl face to base evenly rounded; whorls smooth; base distinctly umbilicated; umbilicus surmounted by strong ridge; aperture elongated, very narrow, widened abapically resulting in teardrop shape; apertural folds or plaits cannot be seen clearly.

Remarks.

The lectotype of this species designated by Fischer and Weber (1997, pl. 14: fig. 1) is much larger and the spire is higher with more whorls than in the present material.
