246 KJELLMAN, THE ALG OF THE ARCTIC SEA. 
sheltered localities. Though it certainly has its typical appearance when growing in 
rock-pools, it is always low-sized at such places, 1—2 feet long. In deeper water 
the typical form even at Finmarken attains a considerable length, even two metres and 
a half. The typical form bears zoosporangia in August on the north coast of Norway. 
On the north coast of Spitzbergen I have collected specimens of f. subtomentosa with 
zoosporangia in course of development in the month of August, and on the west coast 
of Novaya Zemlya specimens with ripe zoosporangia were taken in September. 
Geogr. Distrib. This species seems to be widely disseminated in the Arctic Sea, 
but it is only on the coast of Norway that it is met with in any considerable number. 
Its maximum of frequency is situate south of the Polar Circle. It is not known from 
the Kara and Siberian Seas. The northernmost point where it is certainly found is 
Fairhaven on the north-west coast of Spitzbergen Lat. N. 79° 49’. 
Localities: The Norwegian Polar Sea: Nordlanden common and abundant; Tromsé 
amt, common and abundant about the town of Tromsé; Finmarken at Maasé, Gjesver, 
Oxfjord, and Talvik, pretty common and plentiful. 
The Greenland Sea: the west coast of Spitzbergen, local and scarce. 
The Murman Sea: the coast of Russian Lapland; the west coast of Novaya Zemlya, 
local, scarce. 
The White Sea: rather rare. 
The American Arctic Sea: the north coast of Western Eskimaux-land. 
Baffin Bay: the west coast of Greenland: Tessarmiut, Unartok, Neuherrnhut, 
Godthaab, Kapiselik, Godhavn, Sakkak, and Waygats Strait. 
The typical form is known from the north coast of Norway and the west coast 
of Greenland; f. crassipes from the north coast of Norway (Maasé). At Spitzbergen 
and Novaya Zemlya I have found a form that resembles most nearly f. swbtomentosa.
