Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. A. Darragh 2011 | Shell of five to six whorls, solid, of medium size for genus, globose to subpyriform, last whorl covered with glaze, enveloping the previous whorls, somewhat humped posteriorly with posterior dorsal slope steeper than anterior; smooth dorsal surface. Spire slightly projecting, of 4–5 whorls, covered with thick callus on most specimens. Protoconch smooth, of one whorl merging imperceptibly with teleoconch whorls; beginning of protoconch slightly immersed. Posterior canal with rounded sides, wide, notched, projecting posteriorly on most specimens with prominent solid lateral projections, longer on columellar side. Anterior canal subcylindrical, narrow, deeply incised, reflexed dorsally and supported by thick lateral flanges on most specimens; on large specimens canal considerably extended. Aperture narrow, very slightly curved, slightly wider and steeply sloping inwards at anterior end before anterior canal; outer lip with 24–33 welldeveloped teeth extending along entire lip. Columella with 24–33 strongly developed ridges, extending along entire columella, bifurcating on some specimens, not extending onto fossula. Fossula well developed, concave, broad and spoon-shaped, bounded anteriorly by well-developed single terminal ridge. |
