Original Description

Test biserial throughout, wall microperforate, with pore mounds. Chambers inflated, subglobular in the juvenile, later becoming slightly reniform. Sides of test gently tapering; sutures deeply depressed. Individual chambers with greatest depth near the median suture, pinched near the periphery, to give a subacute periphery. Aperture bordered by elongate flanges, which extend to the opposite edge of the test; relict flanges of earlier chambers often visible along the periphery.
