On the taxonomic status of Cerianthus septentrionalis van Beneden, 1923 (Cnidaria: Anthozoa: Ceriantharia)
T.N. Molodtsova
Abstract. The holotype of Cerianthus septentrionalis van Beneden, 1923 is examined. This species was pretended to have two separate sexes. However as result of close investigation, both types of gonads are found in the holotype. C. septentrionalis is thus a junior synonym of the common North Atlantic species C. lloydii Gosse, 1859 (new synonymy).
