Original Description
Test very low trochospiral with 10-15 chambers, and with 5-6, but occasionally more in the ultimate whorl. The chambers which are globular to slightly ovoid in shape increasevery gradually in size. The arrangement of chambers in the coil is nearly phispiral although the last one m two chambers may be shifted slightly towards the umbilicus. The apeture is interiomarginal, umbilical to extraumbilical, a low to high arch which is bordered by a narrow lip that often is somewhat wider in the umbilical area. The umbilicus can vary from narrow and deep to fairly broad and wide but is open to the previous chambers. The wall is weakly to strongly cancellate and nonspinose.
