and Jugor Schar, Nova Zembla 6^10 fath. (Giard et Bonnier, Bull. 

 Scient. France et Belgique, ser 4, vol 25, 1893, p. 421). 



Diastylis resima is known from Baffins Bay, and H. J. Hansen 

 (1887) mentions some specimens from Krøyer's time from "Green- 

 land", locality not stated. At E. Greenland it has been taken in 

 Hekla Havn (70"27' N.) (H. J. Hansen 1895); further at Spitzbergen, 

 Nova Zembla and west coast of the Samoyede Peninsula. 



Diastylis spinulosa has been taken at W. Greenland from 65° 

 ir N. right up in Murchison Sound, Smith Sound (H.J. Hansen 1887, 

 Ohlin 1895, "Tjalfe") and at E.Greenland in Scoresby Sound (Ohlin 

 1901). It is also known from Spitzbergen, Barents Sea, Franz Jo- 

 sephs Land, Finmarken, Nova Zembla, Kara Sea, west coast of the 

 Samoyede Peninsula and N. of the mouth of the Jenissei; it is thus 

 possibly circumpolar like the next species. 



Diastylis Goodsirii is known from arctic America and at W. 

 Greenland from 65°35' N., right up in Smith Sound (H. J. Hansen 

 1887, Ohlin 1895, Ortmann 1901, "Tjalfe"); at E.Greenland it has 

 been taken from 7043' N. to 74°10'N. (OhHn 1901). It is also known 

 from Jan Mayen, Spitzbergen, Barents Sea, Porsanger Fjord, Vadsø, 

 Kara Sea, west coast of Samoyede Peninsula and N. of the mouth 

 of the Jenissei. 



Cordylochele brevicollis, Nymphon longimaniim and N. Sluiteri are 

 known from E. Greenland to the Kara Sea (Lönnberg 1903, Stuxberg's 

 "Vega", and "Fauna arctica"). 



Pseudopallene spinipes seems from the available material to live at 

 the coasts of Greenland and of the cold area, where it is widely distri- 

 buted; it goes down to 380 m. however and is found in the Kara Sea. 



Nymphon breviiarse has a similar distribution to the preceding, 

 but has been found by the "Ingolf" at 2 stations just S. of the 

 ridge between Iceland and Greenland in very deep water, namely, 65° 

 14' N., 30 39' W., 752 fm., 2.1° C. and 65°24' N., 29°00' W., 735 fm., 1.2° C. 



3D. Arctic littoral species which are found from Green-

circumpolar.
