In the countries nortli of Iceland it is especially the A species
which constitute the greater part of the coinmon species, and the
farther north \ve 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 tlie 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
