Halitat. In the Norwegian Polar Sea this species is usually litoral, 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 alge, f. wncialis 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- 
eality is Lat. N. 73° 20' on the west coast of Greenland. 
Localities: The Norwegian Polar Sea: both the forms common at Nordlanden; 
Finmarken: Gjesveer (f. uncialis) scarce. 
The Murman Sea: (f. typica) rare on the east coast of Novaya Zemlya. 
Bafin Bay: Cumberland Sound (f. typica) abundant; the west coast of Green- 
land, f. wneialis at Omenak and in Whale Sound, f. typica at Lat. N. 73° 20’
