Diagnosis
ReferenceDiagnosis
J. Gründel and H. A. Kollmann 2012The shell is low trochospiral. The adapical whorl face is moderately convex. The sculpture consists of strong collabral ribs which extend from suture to suture. In the last whorl the adapical whorl face is limited towards the convex abapical whorl face by a rectangular carina. It is limited towards the concave base by another carina. The collabral ribs extend into the broad umbilicus.
