206 KJELLMAN, THE ALG OF THE ARCTIC SEA. 
in the Norwegian Polar Sea this is not the case according to Kignn. On the coast of 
Finmarken it is profusely furnished with receptacles during the month of July. In 
August and at the beginning of September I found only sterile specimens. 
Geogr. Distrib, The present species is known only from the Norwegian Polar Sea 
and Baffin Bay. Its maximum of frequency is certainly on the north coast of Norway. 
The northernmost locality where it is known with certainty to live is Gjesver on the 
north coast of Norway about Lat. N. 71°. 
Localities: The Norwegian Polar Sea: Nordlanden pretty common and abundant; 
Tromsé amt at Tromsé and Rend common and abundant; Finmarken common and very 
abundant at Maasd, Gjesver, and Oxfjord. 
Bafjin Bay: the west coast of Greenland at Julianeshaab and Godhavn, according 
to specimens in the herbarium of the Copenhague Museum *).

Remark on the species. In my collections from Finmarken there is a number of 
specimens of a form of Fucus, with which the above-quoted description of F. mielo- 
nensis by AGARDH agrees so completely as to leave no doubt that they are to be re- 
ferred to this species. I have had such a specimen delineated on tab. 19, fig. 1. With 
these specimens that plant agrees very well which Kieren has brought home from Nord- 
landen in great number and named /. dictichus var. miclonensis in his account of the 
marine vegetation of that region. One of his specimens is figured in tab. 19 fig. 2. 
In my opinion it is to be regarded as a distinct species, approaching certainly nearly 
F, jiliformis, but differing from it by spreading or even patent segments, considerably 
broader — even 3 mm. broad — upper segments, more solid structure, shorter, coarser, 
and less swollen receptacles, which are often united in pairs at the base and in that 
case widely distended from one another, and by large, very patent scaphidia. 
That Fucus from Spitzbergen and Greenland which J. G. AGARpH has distributed 
under the name of #. miclonensis does not, as far as I can judge, belong to this species 
as described by himself, but is to be considered as a form of FP. evanescens, according 
most nearly with its f. angusta. This form of Fucus is distinguished from £. miclo- 
nensis as understood by me, by considerably firmer consistency, less distinct costa in ~ 
the upper segments, more numerous and more distinct cryptostomata, and above all 
by smaller and less swollen receptacles which differ less in shape from the sterile seg- 
ments and reach the same height as these. The scaphidia are small and numerous. 
The plant becomes very black in drying, whilst F. miclonensis, if handled carefully in 
') It is by some mistake that FarLow reports this species as taken at Spitzbergen; New Engl. Aly. p. 102.
