Litoral and sublitoral. In the former zone it occurs 

 chiefly at low-water mark and usually fastened to other al- 

 gæ, as Fuci, Chordaria flagelUformis and Cladophoræ. In the 

 sublitoral zone it descends to a depth of about 10 fathoms, 

 generally attached to other algæ, as Chorda filum and Litho' 



thamnia. It appears on open as well as sheltered coasts, 

 and also enters the inner end of the deep bays. The plant 

 beiars gametangia in June, July and August. In the middle 

 of June I found a solitary specimen provided with zoospor- 

 angia together with gametangia (f. siliculosa). 



Distrihufion: Pretty common everywhere and at several 



places abundant,

Litoral and sublitoral, chiefly fastened to other algæ, 

 as Cladophora^ the lamina of Laminaria hyperhorea, L, digi- 

 tåta and the stipe of Alaria. It is only met with on open 

 coast, and it bears gametangia in the later half of June, in 



Jtily and August. 



Distribution: Scattered and rather scarce along the un- 

 sheltered part of the coast, at some places, for inst. Kjolle* 

 ^ord, pretty plentlful.
