as they were gathered from a sandy bottom they were doubtless 
free-floating examples; otherwise I only found them washed ashore, 
and it appears as if the specimens found by other collectors were 
also only such as had been cast ashore; thus, Lyngbye does not 
enter into any details regarding its habitat. I am therefore not 
prepared to say anything definite regarding its habitat around the 
Faeroes, but I believe it grows along fairly open sea-shores and 
probably in the sublittoral zone, as it can only bear a short period 
of desiccation without injury. 
I found it bearing assimilative hairs in June and July. 
It is hardly common along the coasts of the Faeroes. Lyngbye 
(1. c.) writes with reference to it: — »Habitat ad littora Faeroensia haud 
frequens, ut in sinu Qualboe Suderoe, et ad littus Molen prope Eide 
Osteroe«. Rostrup collected specimens of it on the east coast of 
Strom6 where it was also found by me, viz. near Thorshavn and Hvide- 
naes. Again, Simmons observed it near Ejde (Ost.) and I near Kvalbo 
(Syd.), i. e. in the same places where Lyngbye found it.

Found growing in the sublittoral zone down to a depth of 
some 10 fathoms; it rarely occurs at greater depths and Kjellman’s 
statement (1. c.) that specimens were found near Spitzbergen down 
to a depth of 150 fathoms must undoubtedly be due to detached 
floating examples having been carried by the stream to deeper 
waters. 
It grows by preference in the open sea but may also be met 
with in somewhat sheltered situations. It is generally found growing 
attached to stones and rocky bottoms, but also occurs, though rarely, 
as an epiphyte, especially on the stem of Laminaria. 
This is a very common species of the Fseroese coasts, as was pointed 
out by Lyngbye, who writes: — »Ad insulas Fseroenses copiose«.
