198 KJELLMAN, THE ALG^E OF THE ARCTIC SEA. 



such organs in July and August at Nordlanden and Finmarken, in July on the west 

 coast of Novaya Zemlya, and a form which is nearest related to f. arctica at the end 

 of July at Novaya Zemlya. Of f. abbreviata I have seen only sterile specimens. 



Geogr. Distrib. It is known both from the Atlantic and the arctic region of the 

 Polar Sea. In the latter it has but a limited distribution, being probably a form 

 that has immigrated there. It is not known from the Kara Sea, the Siberian Sea, and 

 the American Arctic Sea. If it occurs in Baffin Bay, it must be very local and scarce. 

 The only notice of its occurring there is by Lyngbye, who alleges having seen speci- 

 mens from that sea in the herbaria of Fabricius and Gieseke. During the numerous 

 expeditions which have in later times visited those waters, this plant has not been met 

 with, as far as I know. Its maximum of frequency is on the north-west coast of 

 Norway. The most northern locality where it has been observed is the coast of 

 Spitzbergen. 



Localities: The Norwegian Polar Sea: Nordlanden (f. abbreviata, f. typica and f. 

 angusta) common and abundant; Tromso amt (f. grandifrons and f. typica), the latter 

 form abundant and common; Finmarken (f. typica) common and abundant, at Maaso, 

 Gjesva^r, the south coast of Magero, and Oxfjord; f. grandifrons local and more scarce 

 at MaasO and Gjesvier. 



The Greenland Sea: the coast of Spitzbergen (f. arctica), local and probably scarce. 



The Murman Sea: the coasts of Russian Lapland and Cisuralian Samoyede-land, 

 local and scarce; the west coast of Novaya Zemlya and Waygats; probably everywhere 

 forms most nearly allied to f. angusta and f. arctica. Cp. Gobi and Kjellman 1. c. 



The White Sea: common and plentiful, probably f. angusta and arctica. 



Baffin Bay: the coasts of Greenland, according to Lyngbye.
