Habitat. It grows within the sublitoral zone on exposed coasts, scattered, as an 
element of the formation of Laminariacew. I have found individuals with tetrasporangia 
in August on the north coast of Spitzbergen. 
Geogr. Distrib. It is known only from the arctic region, where it is but little 
spread. Its maximum of frequency is probably in Baffin Bay. Its northernmost locality 
is Fairhaven on the north-west coast of Spitzbergen, Lat. N. 79° 49’. 
Localities: The Greenland Sea: the northwest coast of Spitzbergen, scattered and scanty. 
Bafjin Bay: on the west coast of Greenland. Tere it appears to be pretty com- 
mon. However, I know with certainty only one locality where it is found, namely 
Godthaab.

Habitat. At that place where it has been found in the Polar Sea, it is litoral 
growing beneath Fucus and Ozothallia, according to Kirrx. Only small sterile 
specimens are known from the Polar Sea. 
Geogr. Distrib. It has hitherto been recorded only from one locality in the southern 
part of the Norwegian Polar Sea.
