ieft behind a slightly altered form, G. relictus G. О. Sars (G. loricatus 

 Loven) as a relict in lakes in Norway (Mjøsen), Sweden (Wenner, 

 Wetter, Stora Lee), Finland and Russia (Ladoga, Onega) (Sars, "Ac- 

 count" vol 1, p. 496). 



Amaihilla pingiiis has the following distribution according to 

 Stebbing ("Tierreich") : Greenland, depth 6— 56m., Spitzbergen 4 — 22 m., 

 circumpolar, reaching lat. 82 24' N. — Further, it is found at arctic 

 America (Miers, Ohlin 1895, Ortman 1901, Sars 2nd "Fram" Exped.). 

 At W. Greenland it is widely distributed at any rate down to 90 fm. 

 (Upernivik, H. J. Hansen 1887), possibly much deeper (Lille Karajak- 

 fjord, Vanhoffen). Scott (1899) gives it from Franz Josephs Land 

 and Sars (Crust, in Nansen, "Norweg. North-Polar Exped.", vol 1, 

 1900) from 84° N., 134^ E. 



Unciola leucopis has been taken at W.Greenland from 65°11'N. 

 to Olriks Bay, N. of Cape York (H.J.Hansen 1887, Ortmann 1901); 

 E.Greenland 72°27' N., 19"56' W., ca. 100 fm. (H.J.Hansen 1895), 

 N.Shannon 30 fm. and Germania Havn (ca. 75'/2° N.) (Buchholz); 

 further, Spitzbergen (Goes), Varanger Fjord 90—120 fm. (Sars "Ac- 

 count"), Barents Sea (Hoek), Kara Sea (H. J. Hansen, "Dijmphna") 

 and Siberia (Stuxberg "Vega"). Whether all these localities really 

 refer to this species and not to U. irrorata Say, with which it has 

 often been confused earlier, cannot be seen with certainty from the 

 literature; but there can be no doubt, that they are at least in the 

 main correct, as Sars ("Account") gives most of the localities just for 

 this species, whilst remarking upon the confusion. Stebbing ("Tier- 

 reich" p. 678) gives the distribution as follows "Arctic ocean (widely dis- 

 tributed, depth to 300 m.; Varanger Fjord (Norway), depth 170— 226 m.)". 



Glyptonotiis Sabini has been taken several places at Alaska (teste 

 H. Richardson 1905), arctic America (Sars, 2nd "Fram" Exped.) and 

 at W. Greenland (Julianehaab ca. 6Г N., Ivsugiksok ca. 76° N., 5— 

 12 fm., H. J. Hansen 1887); Barents Sea 77°14' N., 38°26' E., 76 fm. 

 (Stebbing, Ann. Mag. Nat. Hist, ser 7, vol 5, 1900, p. 14) and N. of 

 Siberia, widely distributed both W, of Cape Tjeljuskin and in the 

 eastern part of the Siberian Polar Sea (Stuxberg, Bihang .... vol 5, 

 1880). Further, H. Richardson (1905, p. 350) gives quite a number 

 of localities within the arctic region. 



Dajus Mysidis is widely distributed within the arctic region. 



3E. Boreoarctic littoral species, which range from America 



(or Greenland) to Spitzbergen, but are not found N. of 



Siberia and have their southern boundary in Europe S. 



of Finmarken (a few also live in deeper water).
