FISHES FROM THE SEA-BOTTOM 455 



to Iceland, we shall at the same time trace the limit between 

 the cold-water fauna of the deep basin and the boreal fauna of 

 the slope of the coast plateau. Within this boreal region we 

 may discern different areas of distribution. The ling, for 

 instance, is caught off the coast of Norway in abundance as far 

 north as Lofoten ; north of Lofoten, between the Faroe Islands 

 and Iceland, and at Iceland, the ling is only poorly represented,

while the cod there plays an important part in the "edge"

 in weight, on the other hand, occur on the slope from west of 

 Bear Island, round the North Sea plateau, the Faroe Islands, 

 and on to Iceland. The Norway haddock has a similar distribu- 

 tion to that of the large halibut. 



The fauna of the eastern and southern slopes of the 

 Norwegian Sea thus proves to be very uniform for a distance of
