Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. B. Knight 1941 | Large, high-spired gastropods with a shallow sinus in the outer lip culminating in a slit that gives rise to a selenizone and with revolving ornamentation on the base; whorl profile gently arched; sutures but moderately impressed; base quite flatly rounded, anomphalous; columellar and parietal lips not certainly known; outer lip with a shallow and broad sinus and probably with at least a shallow slit at the position of the selenizone; early whorls unknown; ornamentation, five or more rather wide, rounded, revolving costae on the base, the whorl face being without ornamentation other than the lines of growth and the selenizone; lines of growth numerous and somewhat irregular, passing from the upper suture obliquely backward at an angle of about 13 degrees from the vertical, the angle increasing only slightly as the selenizone is approached, below the selenizone the growth lines passing obliquely forward at an angle of about 23 degrees with the vertical, the angle being somewhat greater close to the selenizone, the course of the growth lines on the base unknown; the selenizone located somewhat below mid-whorl height, its width being about one-sixth the width of the whorl face, its surface flat and commonly impressed below the surface of the whorl face though sometimes above, not bordered by revolving threads or grooves; lunulae indistinct. A large specimen would have something more than 12 whorls and would measure about 120 mm. in height and 45 mm. in width (composite), with a pleural angle of about 32 degrees. |
