Hahitat. Either litoral or sublitoral, attached to other alga3 or to stones, growing 

 scattered both on exposed and sheltered coasts. Kleen has collected it with zoospo- 

 rangia (and gametangia?) at Nordlanden in August. 



Geogr. Distrib. Known from the Norwegian Polar Sea and Baffin Bay. It is 

 uncertain, however, whether the Sphacelaria cirrhosa reported from the west coast of 

 Greenland is really the present species and not Sph. arctica. Its maximum of frequency 

 is at Nordlanden, this being also the most northern place where it occurs. 



Localities: The Norwegian Polar Sea: Nordlanden common. 



Baffin Ba,y: Cumberland Sound; the coast of Gi"eenland according to Croall and 

 Lyngbye 1. c.
