Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M.L. Thein and M.H. Nitecki 1974 | Subturbiniform, narrowly phaneromphalous. Upper whorl surface flattened and rather steeply sloping down to periphery, bearing three revolving cords, one of which is stronger at periphery. These cords are crossed by thinner but sharp, uniformly strong and spaced transverse lirae which are straight and extend backward at an angle of about 10 to 15 degrees from vertical, low nodes being formed at the intersections. Surface below peripheral angulation more progressively convex and then abruptly curved into umbilicus, ornamented by 4 to 5 somewhat weaker revolving lirae. These are crossed by transverse lirae, almost as strong as those of upper surface, which are convex backward. Funnel-like columella reflected over umbilicus. Aperture unknown. |
