This form, and, to some extent, the last, resembles some of the 

 forms of Odonthalia Aleutica, but are more slender and have the 

 branchlets even from the very first, spirally arranged. However, 

 it is not always easy to determine this from dried specimens. We 

 have examined carefully every specimen referred here and feel 

 fairly certain that all belong under this name. 



Rhodomela Lycopodioides f. typica subf. tenera Kjellman. 



Golofnin Bay, Alaska, R. C. McGregor, No. 5674! 



This plant agrees fairly well with Kjellman's figure of this 

 form (1883, pi. 9, f. 2). 



Rhodomela Lycopodioides f. flagellaris Kjellman. 



Golofnin Bay, Alaska, R. C. McGregor, Nos, 5672!, 5677! 



We refer here plants which seem to agree well with Kjell- 

 man's figure of this form (1883, pi. 10, f. 1). 



Rhodomela Lycopodioides f. ramentacea Kjellman. 



In the upper sublitoral zone. Port Clarence, Alaska, Kjell- 

 man (1889, p. 24); Golofnin Bay, Alaska, R. G. McGregor, No. 

 567.""! ! 



We refer the Golofnin Bay specimen here very doubtfully, 

 since it is only a fragment, but it has something of the habit of 

 Chorda /-in abietina described for this form. 



Rhodomela Lycopodioides f. tenuissima (Ruprecht) Kjellman. 



.St. Lawrence Island and Port Clarence, Alaska, Kjellman 

 (1889, p. 24, subf. prolifcra) ; Cape Nome, Alaska, W.A.S., No. 

 5731! (cast ashore); Golofnin Bay, Alaska, R. C. McGregor, 

 No. 5666a!. 



From f. Oladostephus to f. tenuissima is a very considerable 

 jump and were it not for the intermediate forms, it would seem 

 absurd to refer them both under one species. We have had 

 little opportunity of studying this species otherwise than from 

 dried specimens and can hardly express an opinion on this matter 

 or on the relationship between these various forms and forms of 

 R. suhfusca (Woodward) Agardh.
