Two new species are described: Micrura corallifila and Micrura baltica. Complementary descriptions of eight previously known species: Lineus albocinctus, L. bilineatus, L. ruber, L. viridis, Micrura fasciolata, M. purpurea, Cerebratulus fuscus, C. marginatus, and additional notes on the excretory organs of Oxypolella bergendali are given. Most of the material comes from the Bergen area, Norway, the Gullmarfjord area on the west coast of Sweden, and the Baltic. The morphological variability, biology, and ecology were studied. The relationships between the species are discussed. |
