Habitat. It grows sublitoral in 2 — 5 fathoms, attached to stones, scattered, both 

 on exposed and sheltered coasts. At the beginning of August it was provided with 

 zoosporangia in Jiigor Shar. 



Geogr. Distrih. Known from the Spitzbergen province. Nowhere found in great 

 numbers. The most northern point where it certainly occurs is Treurenberg Bay on 

 the north coast of Spitzbergen Lat. N. 79° 56'. 



Localities: The Greenland Sea: the east coast of Greenland at Sabine Island (?) 

 (cp. Zeller 1. c. p. 87); the north and west coasts of Spitzbergen local, scarce. 



The Murman Sea: the west niouth of Jugor Shar, scarce.

Habitat. Having never myself found this species in the Polar Sea, I am un- 

 acquainted by my own observations as to its habitat within that region. It occurs 

 according to Kleen at Nordlanden in the latter part of the summer, epiphytic on Alaria 

 escidenta. 



Geogr. Distrih. Known with certainty only from the Norwegian Polar Sea. It is 

 reported however also from the eastern Murman Sea. 



Localities: The Norwegian Polar Sea: Nordlanden according to Kleen. 



The Murman Sea: the coast of Novaya Zemlya according to Post. et Rupr. (cp. 

 Kjellm. Algenv. Murm. Meer. p. 49).
