128 KJELLMAN, THE ALGJE OF THE ARCTIC SEA. 



it with sporocarps at Nordlanden at the end of July. At the same season I have ga- 

 thered specimens with young sporocarps and ripe tetrasporangia at Novaya Zemlya. On 

 the west coast of Sweden the proper time for the development of the propagative or- 

 gans seems to be in winter, in the months of December and January; however Areschoug 

 states that he has found here individuals bearing sporocarps also in August and Sep- 

 tember. Cp. Aresch. Phyc. Scand. p. 309. 



Geoqr. Distrib. This species is known from the Atlantic as well as the arctic 

 region of the Polar Sea. It is but little spread in the latter and probably is a species 

 immigrated from the south. Its northernmost locality is Matotshin Shar on the west 

 coast of Novaya Zemlya Lat. N. 73° 15', where it occurs in the dwarfed form fastigiata. 



Localities: The Norwegian Polar Sea: Nordlanden, f. typica, common, abundant; 

 Finmarken, f. fastigiata, scarce, local at MaasO, Gjesvter and Oxfjord. 



The Murman Sea: the coast of Oisuralian Samoyede-land, the west coast of No- 

 vaya Zemlya and Waygats, pretty common and plentiful. 



The White Sea : scarce (?).

Habitat. It usually occurs within the litoral zone, attached to other algae. 

 However it has also been found on stones at Nordlanden. In the Polar Sea it grows 

 scattered, chiefly on exposed coasts, bearing tetrasporangia and sporocarps in summer. 

 On the west coast of Sweden I have found it with plenty of tetrasporangia even in 

 winter, at the end of December. 



Geoqr. Distrib. It is known only from the Atlantic region of the Polar Sea. Its 

 most northerly place of growth is Oxfjord in Finmarken at the mouth of Altenfjord, 

 about Lat. N. 70°. Its maximum of frequency is in the southern part of the Norwegian 

 Polar Sea. 



Localities: The Norwegian Polar Sea: Nordlanden common and abundant; Fin- 

 marken: Oxfjord, local, rare.
