Diagnosis

|---|---|---|
| C. L. Garvie 1996 | Shell medium in size, of two and a half whorls with very deeply impressed sutures, the last whorl comprising almost the entire shell. The first one and a half whorls are similar to an Adeorbis, with a globose protoconch that develops stronger spiral sculp' turc on the last whorl. The last whorl making up the adult shell expands very rapidly, opening out trumpet-like, the aperture in a plane parallel to the axis. The outer lip is simple, the columella thin, vertical and defining one edge of a deep but narrow umbilicus. The ornament consists of narrow spiral ribs, 22 on the last whorl, 12 on the preceding.
