Minor septa absent. Columella ordinarily a simple thickened axial plate sur-rounded by intersections of upturned tabulae in transverse section and occasionally abutted by a few septal lamellae. Dissepimentarium composed of 2 to 3 rows of large inflated dissepiments. Tabulae complete, nearly horizontal at the periphery, but deflected upward at the columella, and spaced about 0.5 mm apart.
