Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. E. Eames 1957 | Of medium size to moderately small, calyptraeiform, tending to turbinate, apex markedly eccentric. Whorls strongly convex, with several spirally disposed rows of short, hollow, forward-directed spines together with obliquely disposed threads. Aperture as in Calyptraea, subcircular to suboval. A distinct, sunken, gently concave septum, the margin of which is noticeably concave in its upper part and gently convex in its lower part, occupies nearly half the aperture. A small, deep umbilicus is developed in the upper part of the septum. |
