Q\Q К. Stephensen. 



Acanthephyra purpurea is known both from W. and E. Greenland 

 and from N.America between 31°41'N. and 42°2' N., as also N. W. 

 of the Bermudas. On the east side of the Atlantic it has been taken 

 in the Bay of Biscay, off Portugal, in the Mediterranean and at the 

 Cape Verde Isles. 



Pasiphaë tarda has a similar distribution, but is also known 

 from N. Europe ; thus it is very common in the Skager Rak. 



Parapasiphaë sulcatifrons seems to be western Atlantic; Kemp 

 (1910) records it however from S. W. Ireland. 



Hymenodora glacialis also seems to be western Atlantic, as it has 

 been taken at E.Greenland (but not W.Greenland) and E.America; 

 further, it has been taken W. of Spitzbergen and in the Polar Sea 

 80° N., 134° E. (Sars, "Norweg. North-Polar Exped.", vol. 1, 1900), and 

 Kemp (1906) records it from S. W. Ireland. But it is also found in 

 the Pacific: Bering Sea, Gulf of California, Gulf of Panama and at 

 Ecquador. 



Gennadas elegans and Sergestes arcticus have almost the same 

 distribution as Acanthephyra purp. Sergestes is thus, in spite of its 

 specific name, not arctic but boreal (it is not found for example at 

 E. Greenland). Further, it is also known from Norway and goes 

 southwards to Monte Video, and is found S. of Australia. 



Thysanopoda acutifrons seems to be western Atlantic. The 

 "Tjalfe" has taken it, as new for W. Greenland, at the mouth of the 

 Davis Strait. It goes southwards to 46^'4° N. 



Meganyctiphanes norvegica is found within a region which is 

 bounded by E. America N. of 40° N., S. E. Greenland, Spitzbergen 

 and the west coasts of Europe, as well as Mediterranean at Messina, 

 but it goes further north-east to Siberia and is said to have been 

 taken in the Bering Sea. 



Rhoda Raschii occurs from Greenland to Norway and Scotland. 



Thysanoessa inermis (= Rhoda inermis 4- Thysanoessa neglecta 

 see p. 556, after No. 47) is distributed over the whole North Atlantic 

 and occurs at W. Greenland S. of Karajakfjord (ca. 71° N.); northern 

 boundary is Franz Josephs Land, the south boundary France. Further, 

 it has been taken in the Sea of Ochotsk. 



Also Thysanoessa longicaudata is North Atlantic. 



Nematoscelis megalops occurs in the greater part of the Atlantic, 

 but not between 28° N. and 37° S. The "Tjalfe" has taken it at S. E. 

 Greenland. It is also recorded from the Indian Ocean. 



Gnathophausia zoëa, Eucopia unguiculata and E. sculpticauda go 

 from W. and E. Greenland down into the tropical Atlantic or at 

 least to the Azores and Canary Isles. E. sculpticauda does not seem 

 however to occur at W. Greenland, but all three species are known
