|---|---|---|
| R. L. Batten 1995 | High-spired shells with a prominent upper whorl surface cord and numerous basal spiral cords.
Moderately high-spired trochiform shells with whorls embracing just below center of alveozone. Three early whorls evenly rounded and almost planispiral. Upper whorl surface slightly concave with prominent spiral cord about 1/3 the distance from sharply defined suture to selenizone. Fine spiral lira midway between this cord and upper selenizone margin. Two well-developed spiral lirae border concave selenizone, which has slightly asymmetrical lunulae. Lower selenizone margin forms periphery of shell. Alveozone strongly to slightly concave with one or two spiral lirae confined to upper half. Lower margin ofalveozone on base and equal in development to upper margin. Base flatly rounded with from 8 to 12 spiral cords or lirae. Anomphalus to minutely phaneromphalus. Columellar lip reflexed and ornament resorbed in parietal region. Collabral ornament consists solely of slightly strengthened growth lines on upper whorl surface adjacent to the selenizone and to lunulae within the selenizone. |
