On the north side of Kvalbofjord (Syd,. I found some way inside 

 a cave, rather above Low-water mark a small Phgllophora, 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 habitai 

 answers exactly to whai Batters (Marine Algæ ol' Berwick-onrTweed 

 pp. 3154— .">) savs 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 Færoese speeimens are somewhal larger and more 

 branching than indicated by Batters. I prefer to regard theni as small 

 individuals of this species. 



ACTINOCOCCUS Kutz.

 Chætophora membranifolii Lyngb., Hydrophyt., p. 11; Ch. subcu- 

 tanea Lyngb., Fl. Dan., tab. 2135, lig. 2. 



Parasitic on Phyllophora Brodiæi, on the thallns of which it 

 forms the well-known dark-red, fruit-like growths. The speeimens 

 I saw were sterile. 



Found in the following localities: —Vid. H. J.); Ost: Fuglefjord (!); 

 Syd.: Vaagfjord (H. J.). 



CALLOPHYLLIS Kutz. 



19. C. laciniata (Huds.) Kiitz. Sphærococcus 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 hyperborea\ but also grows attached to stones and shells. 



I have come across speeimens 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 Færoes, as 

 already noted by Lyngbye, 1. c, who writes: — 'Ad insulas Færoenses 

 copiose.« 



Callocolax neglectus Schmitz is a rather common parasite on this plant. 



CALLOCOLAX Schmitz. 



20. C. neglectus Schmitz. Batlers, On some new British Ma- 

 rine Algæ. (Annals of Botany, vol. 9, p. 316). 



This species is rather commonly met with as a parasite on 

 Callophyllis laciniata, and occurs on it in small irregularly shaped
