There are 6-7 whorls, tumid but without subsutural flattening and covered by a thin periostracum. Though smooth to the naked eye there are numerous fine growth lines, prosocline at the adapical suture, orthocline peripherally; older shells usually show equally fine spiral lines. The outer lip is thin, the inner reflected outwards, without an umbilical groove alongside. Last whorl occupies 60-70 % of total shell height, aperture about 50 %.
