Original Description "Axial outline biconvex to convexo-concave. First chambers of the last whorl are rounded, elliptical or ogival, in lateral view, and final ones are ogival or angulous. One keel in the first chambers of the last whorl or in all of them. Spiral side with 2.5 to 3 whorls. Expansion rate between 2 and 3. Between 4 and 6 chambers in the last whorl, separated by nearly radial to rather inclined, nearly straight to slightly arcuate and depressed to raised sutures. These raised sutures are specially common towards the end of the penultimate whorl and the beginning of the last whorl. Spiral outline nearly always lobate, sometimes very lobate. Umbilical side with sutures deparessed, radial to slightly convex towards the front. Large umbilicus, in general more than one-third of the maximum diameter. Interiomarginal, umbilical-extraubmilical primary aperture. Umbilical system apparently formed by large portici." Size: Etymology: Extra details from original publication
