Diagnosis Test robust, planispiral or with slightly irregular early whorls, nautiloid, biumbilicate, chambers inflated, enlarging rapidly, four to five in the final whorl, septa short, straight, thick, following the curvature of the outer wall but bluntly terminated; wall calcareous, finely granular, may be recrystallized or partially replaced and thus appear more coarsely granular or even agglutinated, thick, finely perforate, no supplementary deposits other than thickening of the septa; aperture basal, simple. L. Carboniferous (L. Visean) to U. Carboniferous (L. Namurian); European USSR; Belgium; Czechoslovakia; Denmark; France; Germany.
