208 KJELLMAN, THK 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 Finmarken. 

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

 Norway, about Lat. N. 71°. 



Localities: The Nonoegian Polar Sea: Nordlanden (?); Finmarken at Gjesvaer local 

 and scarce; Norvegia arctica Berggren according to J. G. Agardh. 



The Murman Sea: the coast of Russian Lapland. 



Bafjin Bay: the west coast of Greenland at Godhavn (?) and Siikkertoppen. Cp.

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

 northern Fuci will no doubt gratefuUy aeknowledge the great service done by J. G. 

 Agardii towards elucidating their miitual rehitions in his account of them in Spetsb. 

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

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

 unravelled the confnsed knöt in which those plants were formerly entangled, highly 

 pronioted 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. filiforniis, F. Imearis, and F. midonensis characterized by J. G. Agardh. They 

 stånd 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
