I said before I believe there are hardly any specially marked diffe¬ 
rences between this species and the preceding 1 . 
This species occurs in the littoral zone, but most commonly 
in shallow water and grows usually on stones and shells. I have 
come across cystocarpic plants in April and November. Harvey ella 
mirabilis occurs on it as a parasite. 
Found at the following places: — Syd.: Tvaeraa (!), Vaagfjord (H. J.); 
Kuno (H. J|? 
For Rhodomela sabfusca 0 racemosa Lyngb. see above under Rhodom. 
lycopodioides. 
Under Rhodomela sabfusca Rostrup (1. c. p. 82) writes »Mr. Ran- 
dropp sent us specimens of f. flaccida.^ But the only specimen of this 
form which is preserved in Dr. Rostrup’s private collection does not 
belong to this species, but is a well-developed specimen of Polysiphonia 
elongata. 
ODONTHALIA Lyngb. 
47. 0. dentata (L.) Lyngb., Hydrophyt., p. 9; Kjellm., N. I., 
p. 138 (105). 
This is a sublittoral species and is common both in the open 
sea and in the interior of fjords. It grows on rocky and stony 
bottoms as also epiphytic especially on Laminaria hyperborea. Gene¬ 
rally it occurs dispersed, but it may also be found growing gre¬ 
gariously in small patches. 
Cystocarp-bearing specimens were found in May and December; 
tetrasporic in April, May and June. In the Arctic Sea Kjellm an 
found tetraspore-bearing specimens in August, and Ruprecht (Alg. 
Och., p. 212) mentions having found similar specimens in June. 
Some specimens collected in August in Altenfjord (Kjellman, 1. c. 
p. 106) showed signs of cystocarps. This species seems thus to 
grow much in the same way around the Faeroes as in the Arctic 
Sea. Along the English coasts it bears reproductive organs in the 
winter months. In the Faeroes vigorous young shoots occurred in 
April, May and June. 
This species is very common along the Fseroese coasts as already 
mentioned by Lyngbye (1. c.)| — »Ad insulas Faeroenses copiose.« 
It is recorded by Landt, 1. c. p. 231. 
1 Since writing the above Falkenberg has published his large Monograph on 
the Rhodomelaceae in which he (p. 593) reports R. virgata and R. lycopodioides 
as synonymous with Rh. subfusca, but places a? against this statement.
