Material examined. 25 spms, Stn. 9.

Type locality. Borge Bay on Signy Island (South Orkney Islands), 2 to 20 m depth.

Bathymetric distribution. 0–44 m.

Substrate. Hard bottom.

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

Remarks. It can reach a maximum height of 23.4 mm. During our study it was quite common on the intertidal station 9 at the Lapidary Point. In contrast to the other Trophon species in the area, which were found exclusively in the sublittoral, T. nucelliformis occurred only in the intertidal and was relatively common there. The maximum shell height was 19 mm. This species was already known from the study area from previous Soviet Antarctic expeditions in depths between 3 and 10 m.
