brown tufts of Dichjosiphon foeniciilaceiis , Chordaria flagelliformis, 

 Stictijosiphon tortilis, Ectocarpiis siliculosiis and E. litoralis together 

 with gregarious growths of Phijllitis fascia and Scijtosiplion. Among 

 these darkisli algae the fresh green Enteromorpha Linza hghtened 

 up the vegetation, in which Urospora Wormskioldii, Monostroma fiiscum 

 and otlier green algae were still intermingled. A little farther out 

 in a few feet of water large specimens of Laminaria saccharina were 

 found mixed with the association. 



On the banks of the »Sundene« between Thorsvig and Kvalvig, 

 a very similar vegetation is found. The bottom here is of sand 

 with large stones and pebbles. From the lowest water mark down 

 to a depth of from 3 to 6 feet we find an assemblage of algae of 

 many colours e. g. Cystoclonium piirpurascens . Castagnea virescens, 

 Piinctaria plantaginea, Ectocarpiis siliciilosus and E. litoralis, Diimontia 

 filiformis, Chorda filam, Enteromorpha Linza and several of the 

 above mentioned species. At a short distance from tlie land, where 

 the water is from 4 to 6 feet deep, the Laminaria fceroensis-associa- 

 tion covers the bottom. 



Neither of the two above mentioned tracts are tidal, but a tidal 

 locality with a similar vegetation from the lowest water-mark down- 

 wards to a depth of from 4 to 5 feet is found on the coast of the 

 Vestmanhavn. This vegetation includes: Monostroma fuscnm , Ce- 

 ramium riibriim, Porphijra miniata, Rhodymenia palmata, large 

 » clouds « of Ectocarpus litoralis, Enteromorpha clathrata, Diimontia 

 filiformis, Chorda filum , the upper part of whose thallus floats on 

 the surface of the water, and many more. 



In Vestmanhavn and likewise in Klaksvig, where the vegeta- 

 tions much resemble each other, Halosaccion ramentaceiim, otherwise 

 very rare in the Faeroes, is found. In Klaksvig it grows abund- 

 antly on stones to a depth of a few feet at low water, and it is 

 most often much overgrown by green algae e. g. Enteromorpha, 

 Acrosiphonia, etc. 



In the Danish edition I have called this association »The varie- 

 gated Association «, because of its very motley appearance, due to 

 the many different species which belong to it. But as this name 

 has already, as pointed out by me (10, p. 70), been used by Kjell- 

 man (45, p. 24) I have found it more convenient to change the 

 name, since the association of the Faeroes is quite different from 

 that of Bohusliin.
