The thick shell is external and white in colour, usually with a pear-like shape. The opening is small, but extends the length of the shell. The top of the shell (apex) is sunken. The shell is umbilicated. The shell has a pattern consisting of growth lines. This species is only known from the shell, the length of this varies between 5–5.8 mm.
Occurs in depths from 180–550 m on sand with clay and coral rubble (Sars 1878, Høisæter 2009).
Occurs around Lofoten (Brattegard & Holthe 2001), but there have been reports of specimens from as far south as Risværfjorden (64°59.9 N) (Høisæter 2009).
