Type locality. Wandel (or Booth) Island at the Antarctic Peninsula.

Bathymetric distribution. 2–385 m.

Substrate. Hard and soft bottoms.

Geographical distribution. ANTARCTICA: Circum-Antarctic. SUBANTARCTICA: -. SCOTIA ARC: South Georgia, South Orkney Islands, South Shetland Islands. SOUTH AMERICA: -.

Remarks. In Maxwell Bay and also in Admiralty Bay, this species was found in large numbers in depths of 5 to 90 metres during previous expeditions. In both Fildes Strait and Ardley Cove, we found several hundred specimens in depths of between 15 and 100 m. The shell height was between 2.29 and 2.55 mm. The width was between 1.26 and 1.32 mm. The ratio of height to width was approximately 1.84 to 1.89, which is in the range given by Ponder (1983).
