Habitat. This species is both litoral and sublitoral on the coasts of Norway. In 
other parts of the Polar Sea I have only found it sublitoral, usually in 2—15 fathoms, 
on stony or rocky bottom, as an element of the formation of Laminariaceaw. It is usually 
attached to stones. It prefers exposed coasts, but is not wanting in sheltered localities 
either. Sometimes it occurs gregarious. It has not been found with reproductive 
organs. 
Geogr. Distrib. It is known from all parts of the Arctic Sea, with the exception 
of the Siberian Sea. The maximum of frequency is in the Spitzbergen province. The 
most northern place where it has been collected is Discovery Bay in Smith Sound, 
Lat, N.-8174i . 
Localities: The Norwegian Polar Sea: Nordlanden common; Tromsé amt about the 
town of Tromsé and at Carlsé; Finmarken at Maasé, Gjesver, and Talvik, at all these 
places local but pretty abundant. 
The Greenland Sea: Sabine Island on the east coast of Greenland; it is the most 
common and abundant Phwozoosporacea of Spitzbergen after Chwtopteris plumosa. 
The Murman Sea: the coast of Russian Lapland and Samoyede-land; Kolgujew 
Isle; the west coast of Novaya Zemlya and Waygats common and abundant; the coast 
of the continent at Jugor Shar. 
The White Sea: one of the commonest alge. 
The Kara Sea: Kara Bay; Uddebay. 
Baffin Bay: Cumberland Sound; the west coast of Greenland common according 
to J. G. Acarpu. Known localities: Nanortalik, Smallesund, Fiskernes, Neuherrnhut, 
Hunde Islands, Jakobshavn, Godhavn, Lat. N. 73°20’, Whale Islands, Besselsbay, Disco- 
very Bay, Smith Sound between the 78:th and 82:d latitude.
