Taxonomy
Original description: Test medium to large, slightly trochospiral, evolute; 2-2.5 to 3 whorls; 6 chambers in the last whorl increasing gradually and slowly in size, predominantly pyriform in shape throughout; short, radial prolongations, bearing a single subspherical ampulla except the last one or two bifurcate (rarely trifurcate) chambers which bear two or exceptionally three ampullae; these ampullae exhibit different size and grow asymmetrically with respect to the coiling plane; equatorial periphery strongly stellate; sutures radial, depressed, straight; umbilical area shallow and rather large; aperture straddling the periphery as a low asymmetrical arch bordered by a lip. Wall microperforate, nonmuricate.
