predominate in the northern countries both in growth \ and in 

 number of species (see Rosen vinge's table 71, p. 174); whether 

 tlie same may be said of the Chlorophijcece ^ as the table above 

 seems to indicate, appears to me, however, rather doubtful. At any 

 rate they are very numerous in the littoral and the upper sublit- 

 toral regions of the West-Indies and seemingly predominate there ^. 

 After these remarks we may consider how the Fseroese species 

 are grouped in the above-mentioned five groups. We have the 

 following result: 



arctic species or Vo 



70 subarctic species or 



27 boreal-arctic - 



89 cold-boreal 



29 warm -boreal - 



32.55 Vo 

 12.55 % 



41.4 % 



13.5 % 



It is clear from this table that the cold-boreal species are in 

 the majority in the Faeroes, as not far from one half of the Fseroese 

 algae belongs to this group. Next to that come the subarctic species, 

 including nearly one third of all the Faeroese algae. Of species oc- 

 curring in more southern regions, the w^arm- boreal species, the 

 Faeroes have a little more than 13 ^/o; almost the same number of 

 species must be referred to the boreal-arctic group, w^hich is, how- 

 ever, of less interest from this point of view, as all these species 

 are w^idely spread and often ubiquitous, and at any rate common 

 in all five groups. 



If we leave the Chlorophycece and Cyanophycece out of consi- 

 deration, as they possibly make the result less reliable, the result 

 is nevertheless much the same. 156 red and brown algae in all are 

 found at the Faeroes; that is: 



45 subarctic species or 28.9 % 



17 boreal-arctic - - 10.9 7o 



74 cold-boreal - - , 47.4 Vo 



20 warm-boreal - - 12.8 Vo 



In order to show^ more plainly in w^hich of the surrounding 

 countries we meet with an algae-flora having a composition very 

 closelv connected to that of the Faeroes, and to demonstrate the
