L. nigriijes. Whether such organs are produced even in winter or not, I am unable 

 to deterniine, because in my notes I have confounded this species with L. nigrvpes. At 

 Finmarken and Novaya Zemlya I have found only sterile specimens. 



Geogr. Distrib. In the Polar Sea this species seems to be confined to the Atlantic 

 province and the Spitzbergen province. I did not see it anywhere in the eastern part 

 of the Kära Sea and in the Siberian Sea. It has not been recorded from the American 

 Arctic Sea and the statements of its occurrence in Baffin Bay are uncertain; cp. J. G. 

 Ag. Grönl. Lam. och Fuc. p. 11 and 18. Its maximum of frequency is on the north 

 coast of Norway. The most northern point where it has been taken is the North Cape 

 of Spitzbergen Lat. N. 80° 31'. 



Localities: The Norioegian Polar Sea: Nordlanden, Tromsö amt, for instance, at 

 Tromsö and Carlsö; Finmarken: Maasö, Gjesvter, Öxfjord, Talvik a. s. o.,' common 

 and abundant everywhere. 



l^he Greenland Sea: the east coast of Greenland at Sabine Isle (?), Beeren Eiland, 

 the coasts of Spitzbergen, at the last-named place common and often plentiful. 



The Murinan Sea: common and often abundant on the west coast of Novaya 

 Zemlya and Waygats; Jugor Shar. 



The White Sea: common and abundant. 



The Kära Sea: the east coast of Novaya Zemlya at Uddebay. 



Baffin Bay: the west coast of Greenland at Godhavn and Whale Sound (?). 



Of the forms mentioned f. complanata is known from the coasts of Novaya Zemlya. 

 Here as on the coasts of Spitzbergen there occurred partly a form apparently most 

 nearly related to f. valida, partly f. ensifolia and f. ovata. As for the distribution of 

 the forms on the north coast of Norway the reader is referred to the above-cited work 

 of FOSLIE.

Remark on the species. J. G. Agardh 1. c. has strongly pointed out the chiims 

 of this Laminaria to be regarded as a separate species, setting forth its differences 

 from the L. digitata occurring on the coast of Sweden and south-western Norway. 

 Such a view seems to me very well justified already on account of the reasons brought 

 forward by Agardh. Recent investigations have, however, brought into light some facts 

 that appear to prove that the Laminaria of Scotland and Ireland, the specific difference 

 of which from L. Clustoni I have above pointed out and which has been set down 

 by Harvey as a f. stenophylla of L. digitata, is not identical either with L. Clustoni 

 or with that species which has gone under the name of L. digitata in låter Swedish 

 algological treatises. For it is stated by Cluston that the Laminaria alluded to does 

 not change its lamina regularly, as L. Clustoni, »but the great distinction in this part .... 

 is that the Cuvy» (= L. Clustoni) »annually throws off the old leaf and acquires a new
