germination in January, and during all the winter specimens with young prolifications 
were common. Individuals bearmg nemathecia were collected in November, December, 
January and March. The plant occurring here with such organs even at other season, 
I think it may be assumed to develop reproductive organs throughout the year. In the 
eastern Murman Sea, the Kara Sea, and the Siberian Sea I have seen individuals with 
nemathecia in the months of July, August, and September. 
Geogr. Distrib. One of the commonest and most widely spread alge of the Arctic 
Sea. It is circumpolar, with the exception of not being found within the Atlantic 
province. It has been met with in the greatest number at Spitzbergen and in the 
eastern part of the Kara Sea. The most northerly place where it is known with cer- 
tainty to occur is Treurenberg Bay, Lat. N. 79°56. It may possibly go still farther 
northwards on the west coast of Greenland, as it has been reported from Smith Sound 
between Lat. N. 78 and 82. 
Localities: The Greenland Sea: the coasts of Spitzbergen, common, sometimes 
plentiful. 
The Murman Sva: the coast of Russian Lapland; Kolgujew Isle; the west coast 
of Novaya Zemlya and Waygats, common, but not plentiful. 
The White Sea: common and abundant according to Gost. 
The Kara Sea: the east coast of Novaya Zemlya, Lat. N. 76° 8’, Long. O. 90° 25’, 
Lat. N. 76°16’, Long. O. 92°20', Cape Palander, Actinia Bay, in the last two places 
common and abundant. 
The Siberian Sea: to the west of Blishni Isle, Lat. N. 73°40, Long. O. 140° 6’, 
loose on the bottom; Irkaypi, common, but not abundant. 
The American Arctic Sea: remarked at several places. 
Baffin Say: north of the 78:th latitude in Smith Sound.

Habitat. Litoral or sublitoral in the interior of deep bays in the Polar Sea, 
fastened to stones, muscles, or shells. It has been met with here only as sterile. It 
probably here, as farther to the south, bears reproductive organs in winter. 
Geogr. Distrib. Known only from the southern part of the Atlantic region of the 
Polar Sea. 
Localities: The Norwegian Polar Sea: Nordlanden in Skjersta Bay.
