The article shows the occurrence of jellyfish of the class Scyphozoa along the Norwegian coast. Cyanea capillata and Aurelia aurita have been observed in very varying numbers in recent yraes, most frequently in the south-east with a mass occurrence in South Norwegian waters in 1977. The largestspecimens are found in North Norwegian waters. Of the two blue Cyanea-species C. palmstruchi is a regular resident in South Norway, whereas C. lamarcki is a sporadic visitor from the South. Cyanea palmstruchi has been found north of the Lofoten Is. and Vesterâlen Is. Chrysaora hysoscella has been found in 15 localities between Oslofjord and southernmost Norway (Drobak-Flekkefjord) and 29 specimens have been recorded in the years 1953 - 1978, all of them in the period August - October. Periphylla periphylla has benn found in deep water, mostly between 25 and 1000 m, at several localities between Bergen and Spitsbergen. One specimen outside that range was found near Arendal, South Norway in June 1947. Occasional specimens have been found on the surface or washed ashore. Rhizostoma octopus has frequently been recorded from the Oslofjord around to the Bergen area, as well as twice in the Lofoten Is., mostly in September and October. Conclusion: Four scyphozoans, Cyanea capillata, Cyanea palmstruchi, Aureliaaurelia, and Periphylla periphylla, occur as regular residents in Norwegian waters, whereas three southern species, Cyanea lamarcki, Rhizostoma octopus and Chrysaora hysoscella, occur as infrequent visitors.
