Description : Test large, planoconvex, low trochospiral, spiral side flat, umbilical side strongly convex. Chambers on the dorsal side arranged in 2 — whorls, angular, inflated, the 6 chambers of th'e last whorl, increase moderately in size; on the ventral side the chambers are conical s strongly protrouding with a papillose collar surrounding the umbilicus. Equatorial periphery slightly lobulate to nearly circular, axial periphery with a distinct keel, ornamented with knobs. Wall calcareous perforate, surface roughened with very minute processes, around the "ombilical area rugose. Sutures on the spiral side curved, somewhat raised with bead-like processes; on the ventral side they are straight, radial and strongly depressed. Umbilicus open, wide and deep. Aperture a low arch extending from the periphery to the umbilical area, bordere, by a faint lip. Diameter: 0,52 mm
