This spedes is one of the most comraon of the Florideæ 

 of East-Finmarken, and here too somewhat varying. It ap- 

 pears as a rnle under the form above mentioned, named by 

 Kjellman f. typica a compacta. I have only some few times 

 met with the forms ^ laxa and y tenera] the former at Me- 

 havn and Omgang, in rock-pools between tides, and washed 

 ashore, probably from the uppermost part of the sublitoral 

 zone, and the latter only at Mehavn, in roek-pools between 

 tides. Of the form dadostcpfms, new to the Elora of Nor- 

 way, I found a solitary specimen washed ashore at Mehavn. 

 It belongs to the subform densa, is ab out 10 cm. long, and 

 fuUy corresponds with the description and figures given by 

 Agardh. But, on the other hand, it is nearly allied to f. 

 tjpica a compacta. The oolour is somewhat paler, and it re- 

 tains its colour in drying better than the named form. Two 

 small specimens of a Bhodomela which I also found at Me- 

 havn, in a rock-pool at low-water mark, I have referred to 

 f. flagellaris, formerly only known from Spitsbergen. They 

 are about 3 cm. long and do not fuUy correspond with that 

 form but seem to be a transition between it and f. setacea, 



i 



although most nearly related to the former.
