times quite short and irregularly formed. The sporangia are some¬ 
times sessile, sometimes stalked, and even the larger branches 
sometimes bear sporangia instead of hairs at their apices. The 
chromatophores are ribbon-shaped and are often ramified quite in 
conformity with Kuckuck’s description. The main branches attain 
to a thickness of about 70 p, and the cells have very thick walls. 
This plant which grew in quite shallow water was of a dark, 
yellowish-brown colour. 
With regard to f. hiemalis (Crouan) which is mentioned doubt¬ 
fully by Simmons, 1. c. p. 270, I have not come across any spe¬ 
cimens which I considered could be referred to it. 
Lastly, I may mention that a few specimens, e. g. from an 
open ravine a mile north of Kvivig, resembled in no slight degree 
Ect. penicillatus , but I did not feel justified in referring them to the 
latter species, typical examples of which I have never met with in 
the Faeroes. 
This species which usually occurs as an epiphyte on larger 
algae is common both in the littoral zone and in the sublittoral, 
on open sea-shores as well as in sheltered situations. It has been 
found bearing plurilocular sporangia in May, June and July, and 
unilocular in May and June. 
It was first found along the Faeroese coasts by Lyngbye, and is 
common both as f. typica and as f. arcta ; f. varians I have met with only 
in Sundene between Thorsvig and Kvalvig (Str.). 
86. E. spec. 
In preparing a Laminaria fceroensis from Sundene between 
Thorsvig and Kvalvig, which had been preserved in salt, an Ecto- 
carpus -species was found which I assume to be a new species. 
Unfortunately the material, having been kept so long in salt, 
was somewhat damaged, more particularly the contents of the cells, 
but in spite of this I thought that I could pretty clearly distinguish 
the chromatophores as ribbon-shaped. 
In fig. 69 I have shown some portions of the plant. It is 
rather richly branched, the lower part of the main branches being 
furnished with long branches like themselves, and the upper part 
being most commonly set with short branches only. The main 
branches are about 60 p thick at the base and gradually grow 
narrower, usually terminating at the apex in longer hair-like cells 
which have few chromatophores and are about as long as broad, 
though they vary, being sometimes shorter and sometimes longer.
