Diagnosis Test planoconvex, low trochospire of about five inflated chambers per whorl, enlarging rapidly so that the final chamber occupies about one-half of the umbilical surface of the test, sutures arched and oblique on the spiral side, radial and straight on the umbilical side; wall canaliculate, finely agglutinated, largely of calcareous particles, with a proteinaceous lining; aperture umbilical in position, partially covered by a broad umbilical flap that occupies about one-third of the test diameter, those of earlier chambers remaining visible within the open umbilicus. Eocene; France; Cuba. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
