Ectocarpus fasciculatas is commonly distributed along the coasts of 
the Faeroes; var . refracta has been found only at the following places: — 
Str.: Kvivig(!); Syd.: Kvalbo (!), Frodebo (!), Vaags Ejde (!). 
89. E. granulosus (Engl. Bot.) Ag. J. Ag., Spec. Alg., p. 21. 
Found only in the sublittoral zone at a depth of 2—3 fathoms 
in sheltered stations in the bays and sounds, where it grew epi¬ 
phytic on Laminaria. It has been found bearing plurilocular 
sporangia in the middle of May and at the end of October. 
Found hitherto only near Kvannesund (Vid.) amongst some different 
algae growing on the lamina of a Laminaria gathered by Jonsson; and 
in Trangisvaag (Syd.) on the lamina of a Laminaria (!) and in a seine 
(Ostenfeld).

Among specimens belonging to the typical form, I have come 
across a few examples gathered near Thorshavn in June which 
had involucres round the plurilocular sporangia (fig. 72, e) precisely 
similar to those described and figured by Sauvageau, 1. c., as 
occurring round the unilocular sporangia. 
The specimens referred to the variety (fig. 72, a, b, c, d) are more 
particularly marked by the fact that the form of the plurilocular 
sporangia differs widely from that of the typical plant, besides 
varying considerably in itself, and also by the plurilocular sporangia 
being sometimes stalked. Thus, the sporangia are most commonly 
oblong-ovate and, in contrast to those of the typical species, they 
are broadest some way above the base and frequently taper down 
to it. In the majority of cases they are sessile, but very often 
they have stalks composed sometimes of one cell only, sometimes 
of several, in which case the sporangium may most properly be 
said to occur terminally on a short branch. The sporangia-bearing 
branches are sometimes erect, forming an acute angle with the 
main filament, and sometimes recurved. The sporangia occur as 
in the typical form in rows on the inner (upper) face of the branches. 
The main filaments attain to a thickness of some 50 g, and produce 
numerous rhizoids as in the typical form. The chromatopliores
