Test low trochospiral, chambers spherical three and a half to four chambers in the final whorl increasing moderately in size as added; sutures on both spiral and umbilical sides slightly curved and depressed; surface distinctly cancellate, umbilicus narrow, primary aperture interiomarginal, umbilical, a distinct arch bordered by a rim. The last few chambers show one supplementary aperture opposite the primary aperture.
