276 KJELLMAN, THE ALG OF THE ARCTIC SBA. 
mer, I have not seen any but sterile specimens. It probably bears reproductive or- 
gans in winter here as farther to the south, for inst. on the coast of Sweden. 
Geogr. Distrib. It belongs only to the most southern part of the Polar Sea. At 
certain places on the coast of Finmarken it is still plentiful. The northernmost point 
where it has been found is Talvik in Finmarken about Lat. N. 70°. 
Localities: The Norwegian Polar Sea: Nordlanden at Bodé and on both sides of 
Westfjord, rather common; Finmarken at Talvik abundant. 
Bajjin Bay: the coast of Greenland according to J. G. Ac. Spec. Alg. p. 31, and 
specimens in the herbarium of the Copenhague Museum with no special locality noted.

Habitat. Litoral, attached to other alge, as Rhodomela lycopodioides, Polysiphonia 
fastigiata, Gigartina mamillosa, Ptilota plumosa, and Ft. elegans. In the Polar Sea 
it does not occur anywhere in greater masses. Apparently it prefers exposed loca- 
lities, neither Kieren nor myself having met with it in the interior of deep bays. It 
bears reproductive organs in July and August on the coast of Norway. 
Geogr. Distrib. Found in the Norwegian Polar Sea and the White Sea. It is not 
properly an arctic alga, decreasing both in frequency and luxuriancy towards the North. 
Its most northern point is Gjesver in Finmarken about Lat. N. 71°. 
Localities: The Norwegian Polar Sea: Nordlanden common and abundant; Tromsé 
amt at the town of Tromsé; Finmarken local and rather scarce at Maasé and Gjesver.
