Future investioations will undoubtedly g-reatly modify 

 these lists, and also, though in a very much less degree, the 

 division of the Mollusca into Arctic and Boreal species. 



North and south are not in these papers so much regarded 

 as affecting distribution as the more or less arctic conditions. 

 Thus from a distributional point of view the North Cape^ 

 although really north of the greater part of East Finmark, 

 may be regarded zoologically as to the south, since all 

 boreal species must pass round the North Cape to reach East 

 Finmark, and are also at the North Cape living under less 

 arctic conditions. On the other hand, all South Greenland, 

 Iceland, and the Murman coast may zoologically be con- 

 sidered to be more northern, since their climate is more 

 arctic.
