Alibrotus littoralis is distributed right from arctic America over 

 Greenland and Spitzbergen to Siberia. 



Harpinia plumosa has the same distribution, but is also found 

 at eastern N. America, though not at the northern arctic America. 

 It also occurs perhaps at Norway (Sars: "Account"). 



Acanthostepheia Malmgrenii is found at arctic N. America, locality 

 not stated (Sars: 2nd "Fram." Exped.) and in Murchison Sound, 

 Smith Sound (Ohlin 1895). At W. Greenland it has been taken in 

 Umanak Fjord (H.J.Hansen 1887); E.Greenland 69^25' N., 20^01' W., 

 167 fm. (H.J.Hansen 1895); Spitzbergen (Goes), Franz Joseph Land 

 (Scott 1899), Barents Sea (Stebbing), Kara Sea and the whole of the 

 Siberian Polar Basin, "where it has its true region of distribution" 

 (Stuxberg, Bihang vol 5, 1880, p. 37). 



Oediceros saginatus has the same distribution, but has not yet 

 been found at arctic America. 



Oediceros borealis is known from W. and E. Greenland (Buchholz, 

 Boeck, H.J.Hansen 1887), Finmarken (Sars "Account" ), Siberia ( Stuxberg). 



Paroediçeros lynceus. "No doubt often confused with P. propinqims, 

 so that notices of localities and depths are exposed to some uncer- 

 tainty" (Stebbing, "Tierreich", p. 246). It is noted from arctic America 

 (Ohlin 1895, Ortmann 1901 and Sars 2nd "Fram" Exped.); W.Green- 

 land widely distributed from Friederichsthal (ca. 60° N.) to Ivsugiksok 

 (ca. 76° N.) (H.J.Hansen 1887). At E.Greenland it has been taken in 

 Hekla Havn (70°27' N., H. J. Hansen 1895), Sabine Island, Germania 

 Havn (ca. 74^/2° N., Buchholz) and at 9 places at Danmarks Havn, 

 (ca. 77° N., Danmarks Exped.) Further, at Iceland, Newfoundland 

 (Chevreux, Hirondelle 1900), Spitzbergen (Goes), Franz Josephs Land 

 (Scott 1899), Finmarken, Murman Coast, Kara Sea, Siberia. 



Paratylus Smittii ranges from W. and E. Greenland over Spitz- 

 bergen, Finmarken, Barents Sea and Kara Sea to Siberia. As some 

 of the places recorded lie over deep water, e.g. 69°16'N., 58°8'W., 

 183 fm. (H.J.Hansen 1887) the species is perhaps a deep-water spe- 

 cies belonging to the Group 1 C. 



Rhachotropis aculeata is certainly a circumpolar species (Stebbing 

 "Tierreich"), occurring right from arctic America (Ohlin 1895, Sars 

 2nd "Fram" Exped., Ortmann 1901) to Siberia. 



Rhachotropis fragilis has the same distribution but is not known 

 from arctic America. 



Melita Goësii is known from arctic America, W. Greenland (Ni- 

 vak), Spitzbergen 19—75 m. and Jugor skar (Stebbing "Tierreich"). 



Gammaracanthus loricaius is known from arctic America, W. 

 and E. Greenland, Spitzbergen, Franz Josephs Land, Nova Zembla, 

 Siberia 79 m. This species is interesting from the fact, that it has
