Further Distribution: 



North Atlantic Area, eastern part: 



Spitzbergen (Haeckel 1879, p. 131). 



Barents Sea (Linko 1904a, p. 16 and 1904b, p. 2i8|. In the eastern (coldest) part of the Barents 

 Sea Siaitroplwra is common in the open sea as well as in the neighbourhood of the coast; in the 

 western part it is somewhat scarce in the open sea, and in the summer it is almost never found near 

 the coast. In the unusually cold summer of 1899 it was, however, numerous in Kolafjord and in Eka- 

 terin Harbour. Towards the end of the year, on the other hand, it occurs regularly in the neighbour- 

 hood of the coast, and it seems then to breed in this region, young medusae being found here during 

 the first half-part of the year; towards the spring these young medusse emigrate towards the North. 



White Sea (Wagner 1885, p. 80; Birula 1896, p. 16). Wagner found several specimens, 6 — 

 12 cm wide, in the Solowetsky Bay in July 1880. 



Norway. According to M. Sars (1851, p. 158 and 1863, p. 339) the species is not rare at the 

 coast of Finmarken, where Sars found two specimens, 16 cm wide, in Oxfjord and Hav0sund in the
