Original description: Shell of five segments, subovate, smooth, with none of the strictures expressed externally. Cephalis subspherical with a few circular pores, bearing a short, bladed or smooth conical horn. Collar stricture with four collar pores internally and a vertical pore expressed as a short, horizontally directed tube. Thorax and third segment conical, with circular pores in approximately transverse rows. Fourth segment largest, inflated, with greatest dimension medianly or in the distal half. Uniform circular pores are arranged in longitudinal and four to six, generally five, transverse rows. Area between longitudinal rows raised. Last segment truncate, inverted-conical, with thinner wall and three to five transverse rows of circular to elliptical pores. Distal margin scalloped or even, without a differentiated rim.
