This species generally appears under the forms at- 

 tenuata and genuina, yet the latter less common than the for- 

 mer. The form cornucopice I have only seen at Mehavn, 

 Vardo and Vadso. At the last mentioned place I met with 

 a very slender form of f. attenuata. The present plant is 

 litoral and lives on sandy localities, often at the mouths of 

 streamlets, or on rocks and in rock-pools in the npper part 

 of the zone, more seldom epiphytic on other algæ, as Fuci. 

 It occurs on open as well as sheltered coasts. It has been 

 coUected with zoospores in June and July, at West-Finmar- 

 ken also in August and September. 



Distribution: Pretty common along the whole coast, at 

 several places abundant, as Mehavn, Gamvik and Vadso.

The form of f. racemosa I met with at East-Finraar- 

 ken somewhat differs from the above q^uoted ono distributed 

 by Areschoug. The subelongated main-thread is densely 

 clothed with long and alm ost capillary branches, whicb so-
