Original Description

Translated from French: The test is slightly trochospiral, biconvex and with a weakly lobate periphery. About 20 chambers forming 3 whorls. Rapid increase in size for the 6 chambers of the last whorl. On the spiral side, the semicircular or angular sutures of the chambers meet the internal whorl obliquely; they are curved backwards. The last sutures have a tendency to become radial. Six to 7 reniform chambers visible on the umbilical side. The size of the wide umbilicus, is about a 1/3 of the diameter. The aperture is interiomarginal-umbilical in position. The double keel splits into two only toward the septal side.
