Reykjavik, Aug. 13, 1909. (From phot, by Hesselbo.) The Fucus serratus-association was especially luxuriant in Hafnarfj6r5ur on both sides of the fjord, some distance from the head of it, and occurred lowest of all in the Ffzracece-community. In the Vestmannaeyjar the species grew scattered here and there, but was not found in the most exposed places. Sometimes on ex- posed coasts it was found growing in pools in the middle of the littoral zone. The Epiphytes and Intermixed Species of the Fucus- belt. As is well known, an abundance of epiphytic vegetation exists in the Fucus-beli, at any rate at times. Many of the species grow socially and often occur in such quantities, that they set their stamp upon the vegetation. These species may be divided into those 8*.
