Original Description Test nautiloid, somewhat compressed. All chambers visible from above, only those of the last-formed coil visible from below. About six chambers in the last coil. Chambers increasing gradually in size, sometimes slightly carinated at the periphery. Walls smooth. Aperture at the inner end of the chamber near the umbilical cavity. The regularity of the coiling and of the graduated size of the chambers, and the tendency for the form to develop a carinated rim, has led us to give our specimens a varietal name by which they may be distinguished from other members of the species not characterized by these features.
