Diagnosis Test trochospiral in the early stage, with four to six chambers per whorl, later reduced to triserial, biserial, and finally uniserial, peripheral region of chambers subdivided into alveoles by plates arising perpendicular to the outer wall, the later chambers being almost completely filled with the alveolar partitions; wall agglutinated, surface smoothly finished; aperture a low interiomarginal slit in the early stage, later becoming terminal, subcircular to elongate, without a lip or neck.
