f. typica Kjellm., 1. c. 
Most of the Faeroese specimens bear a slight resemblance to 
subforma compacta Kjellm., a few approach some\yhat to subforma 
laxa Kjellm. 
This species occurs both in the littoral zone, near low-water 
mark, and in the sublittoral, in shallow water. It grows on rocks 
and stones and sometimes in rock-pools. It is found along open 
sea-shores as well as in sheltered localities in the interior of fjords, 
and in narrow sounds, and grows in quite shallow water where 
the tide is not felt. 
Tetrasporic specimens were found in May and June. 
This species, which was already found by Landt (l.c. p.229), is 
fairly common along the coasts of the Faeroes. 
I think Gigartina subfusca 0 racemosa Lyngb. (Hydrophyt., p. 47), 
which Lyngbye reports from the Faeroes ought to be referred to this 
species. The specimen in his herbarium, which is from Kvalbo, is only 
a small fragment, but is noteworthy on account of its copious branching, 
which, in connection with its numerous tetraspores, gives it a different 
appearance. 
46. Rh. subfusca (Woodw.) Ag., J. Ag., Spec. Alg., Vol. II, p. 883. 
Though I am of opinion that it is hardly possible to distinguish 
the present species from the preceding I have followed Kj ell man’s 
definition of species (cfr. N. I., pp. 147—8 (113)) and referred just a 
few specimens to this species. The transverse section of some 
gathered at Tvaeraa showed that the central large-celled tissue was 
sharply defined from the peripheral small-celled tissue and thus agreed 
with Kjeliman’s fig. 4, tab. 8, so that they cannot be Rh. virgata; 
The small branches on the longer ones were distinctly subulate 
and not fusiformed as Kj ell man says is the case in Rhodomela 
lycopodioides. While these characters agree fairly well with Rh. 
subfusca , the specimens (from Tvseraa) referred to this species differ 
from it in being dark-red and not black as Kjellm an mentions 
being the case in Rh. subfusca. In habit the plants resembled fairly 
closely specimens of Rh. subfusca gathered by Le Jolis near Cher¬ 
bourg. Beyond these specimens I have referred only a few to this 
species laying more particular stress on their outer habit; but as
