On the north side of Kvalbofjord (Syd.) I found some way inside 
a cave, rather above low-water mark a small Phyllophora , which occurred 
on the rock as a dense, low covering of a fine, red colour. The single 
individuals were small, hardly more than 2—3 cm. high. This habitat 
answers exactly to what Batters (Marine Algae of Berwick-on-Tweed 
pp. 334—5) says of Phyllophora Traillii Holmes, but it cannot be de¬ 
termined with any certainly as the plant is sterile. Both on this account 
and also because the Faeroese specimens are somewhat larger and more 
branching than indicated by Batters, I prefer to regard them as small 
individuals of this species.

Chgetophora membranifolii Lyngb., Hydropliyt., p. 11; Cli. subcu- 
tanea Lyngb., FI. Dan., tab. 2135, fig. 2. 
Parasitic on Phyllophora Brodicei, on the thallus of which it 
forms the well-known dark-red, fruit-like growths. The specimens 
I saw were sterile. 
Found in the following localities: — Vid. (H. J.); Ost: Fuglefjord(!); 
Syd.: Vaagfjord (H. J.). 
CALLOPHYLLIS Kutz. 
19. C. laciniata (Huds.) Kutz. Sphserococcus laciniatus Lyngb., 
Hydrophyt, p. 12. 
A sublittoral species, found attached down to a depth of 25 fa¬ 
thoms. Occurs both in the open sea and in the fjords, generally 
epiphytic, especially on the haptera and lower part of the stem of 
Laminaria hyperborean but also grows attached to stones and shells. 
I have come across specimens bearing tetraspores in June, 
October and November, and cystocarps in May, June, July, October, 
November and December; hence the plant seems to be able to bear 
reproductive organs nearly all the year round. 
This is a very common species along the shores of the Faeroes, as 
already noted by Lyngb ye, 1. c., who writes: — »Ad insulas Faeroenses 
copiose.« 
Callocolax neglectus Schmitz is a rather common parasite on this plant.

20. C. neglectus Schmitz. Batters, On some new British Ma¬

This species is rather commonly met with as a parasite on 
Callophyllis laciniata, and occurs on it in small irregularly shaped
