This species grows in shallow water down to a depth of a few 
fathoms, especially in sheltered situations. It is consequently com¬ 
mon in the interior of fjords and may even be met with right at 
their head where the water is brackish owing to the fresh-water 
streams entering the sea. It grows by preference on gravelly 
bottoms attaching itself to pebbles and shells, and where the water 
is 1 /2 to 1 fathom deep it often forms a dense growth; the topmost 
part of the thallus may then be seen floating on the surface of 
the water. 
Sporangia-bearing plants were found in May, June, July and 
October. Specimens from the spring months were young and still 
small, during the summer they attained to their highest development, 
while specimens gathered as early as October were more or less 
decayed. It probably dies away completely during the winter, as 
is doubtless also the case along the Danish shores. 
This species is common along the sheltered coasts of the Faeroes.

This beautiful alga was found in the sublittoral zone both in 
shallow water on rocky coasts, and in deeper water (some 5 to 6 
fathoms) in Haraldsund where a strong current was running. Here 
it grew attached to stones and shells associated with Laminaria, 
Alaria and other algae, and occurred abundantly in vigorous ex¬ 
amples several feet in length. 
Fructifying specimens were found in May. Found hitherto only on 
Bordo: Aaerne near Haraldsund (!); Ost.: Molen (!) and Ejde (!).

Fig. 84 represents the form most commonly met with in the 
Faeroes, and the one which I regard as typical. The lamina is 
long and very narrow in comparison. One specimen which was
