Halitat. It occurs in the greatest number and most richly developed on rocky bottom 
within the sublitoral zone at a depth of 83—15 fathoms, and is met with in exposed as 
well as sheltered localities. Specimens taken in the latter part of the summer on the 
west coast of Greenland bear zoosporangia. 
Geogr. Distrib. It belongs to the American Arctic Sea and Baffin Bay. Its most 
northern known locality is Whale Island on the west coast of Greenland about Lat. 
N. 77° 30’. I cannot determine where its maximum of frequency is situate.

and Hudson Bay.
