Habitat. In the Norwegian Polar Sea this species is usually literal, sometimes 

 sublitoral. Those few individuals of the typical form which I have found within the 

 proper Arctic Sea, grew in the deeper parts of the sublitoral zone. The typical form 

 is epiphytic on other algae, f. uncialis is attached to stones or to poles, in the former 

 case partly in spots left bare at low water, partly in rock-pools between tides. Both 

 the forms occur on exposed as well as sheltered coasts, usually gregarious, but not in 

 any considerable number within the Arctic Sea. Specimens with zoospores have been 

 collected in August and September on the coast of Norway, in the middle of Jyly on 

 the west coast of Novaya Zemlya. 



Geogr. Distrib. It is known from the Polar Sea north of the Atlantic, and attains 

 its maximum of frequency on the north-west coast of Norway. The northernmost lo- 

 cality is Lat. N. 73° 20' on the west coast of Greenland. 



Localities: The Norwegian Polar Sea: both the forms common at Nordlanden; 

 Finmarken : Gjesvser (f. uncialis) scarce. 



The Murman Sea: (f. typica) rare on the east coast of Novaya Zemlya. 



Baffin Bay: Cumberland Sound (f. typica) abundant; the west coast of Green- 

 land, f. uncialis at Oraenak and in Whale Sound, f. typica at Lat. N. 73° 20'
