During the 2nd Italian Oceanographic Antarctic Expedition (1989–90) a small number of nudibranchs was collected at Terra Nova Bay (Ross Sea, Antarctica). In addition to well known species (such as Austrodoris kerguelensis Bergh, 1884 and Tritoniella belli Eliot, 1907) other, more unusual, species were also recorded, including Pseudotritonia gracilidens Odhner, 1944 and Cuthona georgiana (Pfeffer, 1884). Comparative information on the principal diagnostic features of the numerous species of Cuthona from the Sub-Antarctic and Antarctic waters is also tabulated and discussed.
