extends far above high-water mark on sloping rock faces in much 
exposed localities, where it occurs as an undergrowth under other 
algae, e. g. Porphyra, Fucacece , etc.; at such high levels it is only 
reached by the spray. Near Bosdalafos on Vaago it has been found 
growing some 80 feet above sea-level. It is also very often found 
covering the sides of rock-pools in association with Ralfsia verrucosa 
and different species of Lichens. It is always of a tine, dark crimson 
colour, even when growing in broad daylight, and such bleached, 
yellowish examples as those which occur along the Danish shores 
I never met with in the Faeroes, owing of course to the sky being 
so often overcast and perhaps more particularly to the period of 
sunshine being always so short in the latter place. Rosenvinge 
(Gronl. Havalg., p. 826) has noticed the same to be the case in 
Greenland. 
Tetraspore-bearing specimens were found in March, May, June, 
July, November, December, and it is doubtless able to fructify all 
the year round. 
This species is extremely common along the coasts of the Faeroes.

The specimens referred to f. typica usually agree fairly well 
with Kuckuck’s figure 3, 1. c. The thickness of the main filaments 
varies with an average of 27 y. In fig. 66 is shown one of the 
specimens — gathered at Thorshavn — which I have referred to 
f. pygmcea ; it occurred as a short, densely matted growth on the 
stem of Laminaria digitata. The erect filaments, which are about 
12—13 y thick, are sometimes found bearing only one terminal
