Remark toiiching the naine and the fonns of the species. It seenis to be beyond a 

 doubt that the plant figured and described by Gunnerus under the rame of Fucus 

 pectinatus 1. c. and tab. 2 fig. 8, is the same that goes at pi^esent commonly under the 

 naine of Ft. serrata Kutz. For this reason I have adopted that denomination. Gobi 

 denies its right to be regarded as a separate species, and I must allow that among the 

 specimens, certainly several thousands in number, that have passed between my hands, 

 there have been some few that were allied in character both to Ft. plumosa and Ft. 

 pectinata, although it was scarcely ever difficult to decide to which of these species 

 they ought with more reason to be referred. Having in general found Ft. pectinata 

 independent, I do not hesitate to let it remain a separate species.
