In the countries north of Iceland it is especially the A species 
which constitute the greater part of the common species, and the 
farther north we go, the more numerous are the A 3 species. 
In the countries south of Iceland the reverse is the case; here 
comparatively the greatest number of the common species belongs 
to the E groups. In Scandinavia and Finland the proportion of the 
A groups to the E groups is approximately as in Iceland. 
The table shows the distribution of the species groups illustrated 
exclusively by the quantitative relation of the species to each other. 
The facts relating to the distribution would, however, appear much 
more distinctly if the frequency of the species in the separate coun- 
tries were taken into account, and a classification were worked out 
for Scandinavia. 
II. The Distribution of the Species Groups in Iceland. 
Below in table 5 the quantitative relation between the species 
groups has been calculated in per cent partly of the number of
