Four new species of Polychaeta are described from Subantarctic Marion Island. Orbiniella dayi sp. nov. (family Orbiniidae) occurs from mid-tide levels to depths of 15 m and is separated from Orbiniella minuta Day, 1954, from Tristan da Cunha, by its larger size and the presence of a small post-setal lobe to the parapodia. Scolelepis marionis sp. nov. (family Spionidae) was buried up to 0.5 m in sandy substrata in shallow subtidal depths. It is closely related to Scolelepis lamellicincta Blake & Kudenov, 1978, from Australia, but can be distinguished by its notosetae, which are all capillaries, and neurosetae of bifid hooded hooks that occur from setigers 42-46 and posteriorly. Malmgreniella fimbria sp. nov. (family Polynoidae) is tentatively placed in the genus Malmgreniella, but the presence of a sixteenth pair of elytra distinguishes the species and requires an expansion of the definition of the genus. Malmgreniella fimbria was dredged from a depth of 410-644 m between Marion and Prince Edward islands. Lanice marionensis sp. nov. (family Terebellidae) was previously referred to as Lanice flabellum. Lanice marionensis sp. nov. occurs at depths of 5-475 m on soft sediments.
