Apex curved, with central rosette, In well-calcified specimens, spirals become thinner in periapical zone, then recover thickness at ends, General shape spheroidal to prolate-spheroidal, Spirals in most instances with granulate surface, Basal plate undivided, as thick as wide, with upper and lower faces commonly stellate, visible from exterior, Size generally small. [FEIST-CASTEL
