L. nigripes. Whether such organs are produced even in winter or not, I am unable 
to determine, because in my notes I have confounded this species with L. nigripes. 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 Kara 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. 
Ac. Groénl. 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 Norwegian Polar Sea: Nordlanden, Tromsé amt, for instance, at 
Tromsé and Carlsé; Finmarken: Maasé, Gjesver, Oxfjord, Talvik a. s. 0., common 
and abundant everywhere. 
The 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 Murman Sea: common and often abundant on the west coast of Novaya 
Zemlya and Waygats; Jugor Shar. 
The White Sea: common and abundant. 
The Kara Sea: the east coast of Novaya Zemlya at Uddebay. 
Bafjin 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 Fosrim.

Remark on the species. J. G. AGarpu |. c. has strongly pointed out the claims 
of this Laminaria to be regarded as a separate species, setting forth its differences 
from the JL. 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 Acarpu. 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 £. 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 ZL. digitata in later Swedish 
algological treatises. For it is stated by Crusron that the Zaminaria alluded to does 
not change its lamina regularly, as L. Clustoni, »but the great distinction in this part... . 
is that the Cuvy» (= ZL. Clustoni) »annually throws off the old leaf and acquires a new
