This form much resembles Phycoceris racemosa Kirz. (Tab. Phyc. 6, tab. 26) in ha- 
bit. In structure it coincides very closely with /. complanata var. subsimplex Aruscu. 
(AhIn. Enterom p. 29), but it has somewhat narrower and less regular cells with some- 
what more abundant endochrome. 
Habitat. A litoral alga, attached to stones, growing scattered both on exposed 
and sheltered coasts. On the north coast of Norway it bears zoospores (gamets?) in 
August and September. 
Geogr. Distrib. Known only from the Atlantic region of the Polar Sea. Its 
northernmost point is Maasé about Lat. N. 71°. 
Localities: The Norwegian Polar Sea: Finmarken at Maas6é and Talvik, loca 
and scarce.

Habitat. This species, wherever hitherto found, formed dense, rather extensive 
inmats within the litoral zone on flat rocks that sloped towards the sea and were moist- 
ened at low tide by snow- and ice-water dropping down. 
Locality: The Murman Sea: Besimannaja Bay on the west coast of Novaya 
Zemlya.
