Original Description
"Exhibits variation in the shape of the periphery, convexity of the spiral surface as observed in the axial view, surface ornamentation, and width of the umbilicus. Diagnostic characters of this species are 1) the strongly spiroconvex test; 2) the 3 ultimate chambers which increase rapidly in width, resulting in the initial spire being asymmetric and offset toward the peripheral margin, and 3) the strongly curved, depressed spiral sutures and radial, depressed umbilical sutures."
