): Shell pupoidelongate, without umbilicus. Teleoconch smooth or with axial or spiral sculpture. Protoconch paucispiral, domeshaped, sculptured with minute pits arranged in spiral lines.

Operculum oval, corneous, with two layers, eccentric nucleus, peg usually absent, or small when present; longitudinal cord absent, may have one thread around the margin.
