From tliese tables, it will be seen that Malangen, Kvsenangen 

 and the fiords of East Finmark for the most part have the same 

 molluscs. It is probable that further investigation would show a 

 still greater similarity than that found in the tables. It may, 

 however, with certainty be affirmed, that there are more boreal 

 forms in Malangen and Kvtenangen than in the East Finmark fiords, 

 in the latter there are. on the other hand, more arctic species. 

 The warm current which flows northwards also exerts some influence 

 in East Finmark. On !S / 4 1899, at the mouth of the Porsanger 

 Fiord, at a depth of 250 mtrs., I registered 2".7o C. (p. S). which 

 proved that a comparatively warm current was seeking to pene- 

 trate at the bottom. The temperature at a depth of 200 mtrs. was 

 1.3 and salinity 34.54. 



According to Gran, on Aug. 28th 1900, at the mouth of the 

 Porsanger Fiord, the following conditions were registered from
