Abstract
‐Six entoprocts are reported and figured from the Antarctic Region, collected by the Swedish Antarctic Expedition 1901–1903. The species are: Barentsia discreta (Busk, 1886), Pedicellina cernua (Pallas, 1774), Loxosomella antarctica sp.n., Loxosomella murmanica (Nilus, 1909), Loxosomella compressa Nielsen & Ryland, 1961, subsp. antarctica ssp.n., and Loxosomella brachystipes sp.n. The original diagnosis by Robertson of the genus Myosoma is discussed on the basis of the muscle strands in the calyx and the stalk.
