Description

Phaceloid, increase intracalicinal; epithecal scales may occur; each thick septum composed of thick, contiguous trabeculae arranged in an asymmetrical arch whose axis is close to periphery, the adaxially curving trabeculae being very long, becoming horizontal, and those of major septa being deflected upward in outer parts of tabularium; major septa equal, withdrawn from axis leaving axial space, minor septa shorter; interseptal loculi very narrow to suppressed, dissepiments very small and globose [curvature of trabeculae suggests presence of peripheral pipe of horseshoe dissepiments]; tabulae in axial space horizontal or shallowly concave, mostly complete.
