tation must certainly greatly resemble thai of the Fseroes, as all 

 the forms named by Strom felt are, according to my definition of 

 species, similar to or at least closely connected with Fuciis inflaius 

 f. disticha (compare Jonsson 41, p. 184). 



As to Greenland, Rosen vinge writes (71, p. 199) as follows: 

 Where the coast is exposed to the dashing of the waves, the vege- 

 tation bears a totally different stamp. The Fiicacece are either 

 entirely absent or limited to deeper clefts in the rocks or to pools 

 (Fiicus inflatiisj«. 



It has since been said by Simmons (66, p. 178), that this 

 circumstance may be due to the ice. This may possibly be true 

 in some cases, but probably not in all. 



In describing the algae vegetation of the Murman Sea, Kj ell- 

 man w^'ites (44, p. 59), after pointing out that all littoral algae are 

 low: y>Fuciis evanescenSy welche am haufigsten innerhalb des lito- 

 ralen Gebietes angetroffen wird, scheint mir mit Recht den Namen 

 (f. nana) zu verdienen, den ich ihr gegeben , denn sie ist selten iiber 

 6 ctmr. hoch und immer sehr schmal«. There must likewise be 

 some resemblance between this and the Fseroese vegetation. 



It may be supposed, that Fucus spiralis is found on the Ork- 

 neys in localities resembling those in the Faeroes (see Traill, 81, 

 p. 316, who calls it Fucus platycarpus). If Fucus anceps, as I think ^, 

 ought to be regarded as a form of Fucus inflaius f. disticha, the two 

 characteristic forms of the Faeroese formation are found on the 

 w^est coast of Ireland. At Biarritz Sauvageau^ has found some 

 quite small specimens of Fucus spiralis, which certainly grew on 

 an exposed coast there. On the northern side of Kullen, on steep 

 rocks a little above the sea level, I have met with a dwarfish form 

 of Fucus spiralis, that is, a very similar vegetation, only that Fucus 

 inflaius f. disticha is also wanting here.

The above-mentioned types of vegetation have their habitats 

 above the easilv distinguishable white line formed bv Balanus and 

 bivalves. We shall deal next with an association growing in and about 

 this » animal association «, which is found at about the highest water
