Cerion (Maynardia) maynardi Pilsbry and Vanatta, 1895
"Cerion (Maynardia) Maynardi P. and V.
Shell large, strong, cylindrical, white or fleshy in the intervals between strong, slightly curved ribs, separated by three times their width on the cylindrical portion, which consists of 3 to 4 whorls; those above forming a short cone on which the ribs are much closer. Whorls 11½, flat, the last ascending, becoming attenuated downward, but with well rounded base, upon which the ribs are obsolete, but replaced by fine costulae. Umbilical rimation very deep, the area below it rather wide, bounded by a spiral groove well within the basal margin of umbilical tract. Aperture ovate-truncate, brown within; parietal lamina very strong, thick but short; axial lamina small, one whorl long. Peristome stout, broadly reflexed, its face convexly thickened but not "duplicate;" broadly vaulted over the umbilical region; parietal callus varying from thin to heavy. Alt. 35; diam. 15 mm.; apert. alt. 14; width 12 mm. Some specimens fall under, some exceed these dimensions. Abaco, Bahamas. (Robert Swift. ) Larger and coarser than C. abacoensis, and with far deeper umbilical rimation and distant ribs." (Pilsbry & Vanatta, 1895:209-210)
