Original Description
Test small to medium sized, trochospiral, strongly spiroconvex, umbilico-concave. Spiral side strongly convex, umbilical side strongly concave. Equatorial periphery subquadrate or subcircular to ovoid furnished with a small imperforate peripheral band. Axial periphery truncate, semicircular. Chambers arranged in 2-2.5 whorls. The initial chambers are small and globular and are followed by larger petaloid and inflated chambers. The final whorl is composed of 3-4, larger, petaloid and compressed chambers which increase rapidly in size. In some specimens these chambers are almost vertically directed. The sutures on the spiral side are slightly curved and depressed; on the umbilical side they are radial, straight to occasionally slightly curved and more depressed. The umbilicus is small and deep and is covered by the tegilla. The primary aperture is in an interiomarginal extraumbilical-umbilical position. A few accessory apertures occur in a infralaminal position. Surface smooth, perforate both spirally and umbilically, except the marginal band and the tegilla.
