Report on the Malacostraca, Pycnogonida and some Entomostraca. 605 



Onisimus Edwardsii is very common in arctic America and W. 

 Greenland (Miers, H.J.Hansen 1887, Ortmann 1901); at E.Greenland 

 it has been taken by the Danmark Exped. In America S. of Green- 

 land it does not seem to be known; on the other hand, it has been 

 taken at Jan Mayen, Iceland, Spitzbergen, Franz Josephs Land, 

 Murman Coast, Kara Sea and Siberia and goes along the coast of 

 Norway to Bohuslän and the Kattegat. 



Onisimus plautus has almost the same distribution but is not so 

 common at W. Greenland, whereas at E. Greenland it has been taken 

 at 3 places at ca. TéVa^'N. (Buchholz) as well as by the Danmark 

 Exped. Chevreux ("Hirondelle" 1900) gives it from Newfoundland. 



Orchomene minutas is known from arctic America (Ohlin 1895) 

 and is very common along W. Greenland almost from the south 

 point right up into Smith Sound (H. J. Hansen 1887, Ohlin 1895). 

 From E. Greenland it is given from Hekla Havn (70°27' N., H. J. 

 Hansen 1895). It goes along the Norwegian coast to the Skager Rak 

 and is recorded with some doubt from the British Isles and the 

 Mediterranean. 



Orchomene serratus has been taken as new for Greenland by 

 Due d'Orleans 1907; it has also been taken by the Danmark Ex- 

 pedition. It is also known from Norse Island at Spitzbergen, Siberia 

 and Norway 56 — 188 m., but it is not yet known from arctic America 

 or W. Greenland. 



Pontoporeia femorata belongs to the commonest Amphipods at 

 W. Greenland ; further, it has been taken at arctic America (Sars 

 2nd "Fram" Exped.) and at E. Greenland in Hekla Havn (70°27' N., 

 H. J. Hansen 1895) and by the Danmark Exped. To the south it 

 goes through the Kattegat into the Baltic. 



Monoculodes borealis has been taken at W. Greenland from Godt- 

 haab (ca. 64° N.) to Olriks Bay N. of Cape York (H. J. Hansen 1887, 

 Ortmann 1901) and at E. Greenland by the Danmark Exped. At 

 Norway it is found N. of Trondhjem ; Scotland is its southernmost 

 habitat. 



Pleustes panoplus has been taken at a number of scattered 

 stations in W. Greenland almost from the south point right up into 

 Smith Sound (H. J. Hansen 1887, Ohlin 1895, Ortmann 1901), as well 

 as at arctic America ; at E. Greenland it has been taken at Sabine 

 Island (Buchholz) and by the Danmark Exped. In Norway it oc- 

 curs N. of Bergen. 



Atylus carinatus is known from arctic America and from some 

 scattered places along the whole west coast of Greenland (Miers, 

 H. J. Hansen 1887, Ives 1891, Ohlin 1895, Ortmann 1901). It is 

 mentioned from E. Greenland by Buchholz and H. J. Hansen 1895,
