Remarks. Nucula falklandica from the 26 th Soviet Antarctic Expedition from King George Island, which is housed in the Zoological Museum Hamburg, is illustrated in Engl (2012). Rauschert (1991) published his findings from the 26 th (1980–1982) and 30 th (1984–1986) Soviet Antarctic Expedition from Ardley Cove near King George Island. The provenance of these records is almost exactly the same as that of the present study. At that time, he detected the species at 12 stations in depths between 5 and 70 metres. In the present study we observed this species between 35 and 70 m.
