Remark on the species. By the examination I have made of the Fuci of northern 
Norway I feel justified in adopting J. G. AGarpn’s opinion that the alga named by 
him F. distichus ought to be considered a valid species. Kieren has denied its being 
different from F. filiformis and F. linearis; but he has apparently never known that 
form which J. G. AGArpu understands by the name of F. distichus. At least it is not 
to be found in his collections, forms of F. filiformis passing there under that name. 
Nor does Gopr seem to have met with it in those collections from the White Sea and 
the western Murman Sea which he has examined. On the coast of Norway it is in 
my experience much more rare than F’. jiliformis, from which it is pretty easily di- 
stinguished on closer examination. 
Habitat. The same as the preceding species. On the north coast of Norway 
it still bears receptacles, though rather scarce, at the end of July. In August it was 
only found sterile. June and the beginning of July seem to be its proper fruiting 
season here. 
Geogr. Distrib. Known only from the Norwegian Polar Sea. The northernmost 
point where it has been found is Gjesver about Lat. N. 71°. 
Localities: The Norwegian Polar Sea: Nordlanden at Bodo (f. robustior) scarce; 
Finmarken (f. tenuior): Maasé and Gjesver, at both places rather local and not abundant.
