Original Description
Test trochospiral, flattened spirally and umbilically; periphery truncated by wide double keel. Chambers arranged in two to two and one-half whorls; usually six to seven chambers in final whorl. Chambers in final whorl crescent-shaped to petaloid spirally, but distinctly wedge-shaped umbilically. Sutures on spiral side curved, slightly raised, usually not beaded; sutures on umbilical side straight, radial, depressed. Umbilical side of test often with coarse, beadlike, rugosities on chamber surfaces. Stout portici with infralaminal accessory apertures extending out into a small umbilicus. Primary aperture interiomarginal, extraumbilical in position, a slightly arched opening. Outer wall radial hyaline perforate except for double keel which is radial hyaline imperforate. Septal walls microgranular hyaline sparsely perforate. Portici microgranular hyaline probably sparsely perforate.
