The northern part is remarkable for its great number of species, 

 whereof 19 are alp. arct. The special conditions required for the 

 existence of an abundance of species may exist on these 2 islands, 

 where the lower parts are much more sheltered from the often 

 violent westerly winds. The larger area also gives greater variety 

 of localitv than do the smaller islands. 



THE EASTERN PART (E.), 



ab. 224 n kilom., contains the 6 islands which belong to the Nordreoer, 

 they are, Kalso, Kuno, Bordo, Videro, Svino and Fuglo. These 

 islands consist of mountains, rising partly from the sea to a height 

 of ab. 800 m. Compared with the area the number of species is small, 

 owing partly to the small area of the single islands, partly to the
