208 KJELLMAN, THE ALG^. OF THE ARCTIC SEA. 



not found it in his rich collections of Fuci made here. I cannot decide where it reaches 

 its maximum of frequency. According to my own experience it is rare at Finraarken. 

 The most northerly place where it has been taken is Gjesvaisr on the north coast of 

 Norway, about Lat. N. 71°. 



Localities: The Norwegian Polar Sea: Nordlanden (?); Finmarken at Gjesvser local 

 and scarce; Norvegia arctica Berggeen according to J. G. Agaedh. 



The Murman Sea: the coast of Russian Lapland. 



Baffin Bay: the west coast of Greenland at Godhavn (?) and Sukkertoppen. Cp.

Remark on the species. Every algologist who has studied or intends to study the 

 northern Fuci will no doubt gratefully acknowledge the great service done by J. G. 

 Agaedii towards elucidating their mutual relations in his account of them in Spetsb. 

 Alg. Till. As far as I can judge, Agaedh, as was to be expected from such an ex- 

 perienced, sharp-eyed, and learned algologist, has almost everywhere hit upon the truth, 

 unravelled the confused knot in which those plants were formerly entangled, highly 

 promoted a clear view of the series of forms, and laid a sure foundation for the future 

 study of these series. Among the most difficult forms are those which belong to the 

 species F. filiformis, F. linearis, and F. miclonensis characterized by J. G. Agaedh. They 

 stand pretty distant from certain species, but nearly approach others in certain respects, 

 and in some of their forms resemble each other so closely as to make it sometimes
