Diagnosis Test in a low trochospiral coil of few rapidly enlarging and inflated chambers, periphery broadly rounded, sutures depressed, curved and oblique on the spiral side, radial around the open umbilicus of the opposite side, chamber subdivided by an internal partition that just reaches the dorsal chamber wall but is not attached to it, serrate free edge of the partition curved down toward the aperture; wall calcareous, aragonitic, surface smooth and polished but may have low tubercles around the umbilicus; aperture a wide interiomarginal and wholly umbilical slit, extending from the point of attachment of the final chamber to the previous whorl, across the umbilicus at the base of the bulge of the apertural face, to the very small notch at the opposite end of the bulge at the position of the lower end of the internal partition, primary aperture closed as a new chamber is added and a large ovate intercameral foramen is produced by resorption above the internal partition in the septal face, the bulge of the apertural face also being replaced by a thin plate that extends from the umbilicus to the partition at the base of the intercameral foramen. L. Cretaceous (Albian) to Paleocene; Europe; North America. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
