nearly related to f, flaccida, but it ought perhaps tobekept 

 distinct. I think to have seen it also at Finmarken. 



The species in question islitoral, growing in tidal pools 

 epiphytic on other algæ, nsually Fuci, sometimes also Chor- 

 daria flagelliformis , or fastened to stones.' The plant occurs 

 on open coast as well as in the inner of deep bays and 

 seems to prefer somewhat sheltered localities. Itbears zoo- 

 sporangia in Jnne (f flaccida), and in July and August (f, 

 typica). 



Distrihutiom Common and plentiful almost everywhere.

In the eastern part of the district I collected a few 

 speciraens of a Dictyosiphon, which I have referred to this 



r 



species. They do not fully coincide with specimens from 

 Novaya Zemlya, but no doubt they are referrible to the 

 present species. The short secondary branches are less nu- 

 merous than by the named specimens, and the plant much 

 reminds of D. foeniculaceus f. flaccida. The plant grews in 

 the litoral zone attached to Scytosiphon lo7nentarius , bearing 

 zoosporangia in the beginning of August, but sparingly. 

 Distribution: Found only at Vardo, rare.
