Specimens bearing unilocular sporangia were observed in July. 

 I'ound hitherto only on Sir.: Kvivig (!), Gliversnæs (!). 



114. S. cæspitula Lyngb., Hydrophyt., p. 105. 



Found hitherto in the Færoes only by Lyngby e, who writes 

 with reference to it: - - »Habitat ad stipitem Laminariæ digitatæ 



ad littus Færoense rarius«. The specimens in Lyngbye's Herbarium 

 are from Næs on Ostero. 



115. S. cirrhosa (Roth) Ag. 



Regarding the specimens I have referred to this species, Sau- 

 vageau writes to me: — »c'est en effet ce que l'on apelle le S. cir- 

 rhosa. Mais je n'ai pas encore terminé l'étude de cette espéce pour 

 mon mémoire en cours de publication, et je serai peut-étre obligé 

 de la scinder en plusieurs autres«. Until then I report it under 

 this name. 



This species has been found epiphytic on Desmarestia aculeatu 

 and Chætomorpha Melagonium in exposed as well as in sheltered 

 localities. Specimens bearing propagula were met with in December. 



Found hitherto only on Svino (H. J.); Syd.: Vaagfjord (H. J.). 



116. S. furcigera Kutz. 



A Sphacelaria which I had gathered near Thorshavn on a La- 

 minaria Sauvageau has determined as this species. Sauvageau 

 writes to me concerning it: — »Bien que cela puisse vous étonner, je 

 considére cette espéce comme le S. furcigera, qui n'est pas exclusive- 

 ment tropical comme on le dit. C'est cette plante que Pringsheim 

 a représenté comme S. olivacea å propagules, et M. Kuckuck comme 

 S. furcigera var. saxatilis. Récemment M. Kuckuck (in litt.) revenait 

 å l'opinion que ces propagules appartenaient au S. olivacea, mais moi, 

 je tiens pour le furcigera«. 



This plant has been gathered from 3 — 4 fathoms of water 

 where it grew on the stem of a Laminaria in a fairly exposed lo- 

 cality. It had propagula in May. 



Found hitherto only on Str. : Thorshavn (!). 



CHÆTOPTERIS Kutz. 



117. Ch. plumosa (Lyngb.) Kutz. 



In Rostrup's list (l.c. p.86) this species is mentioned as found 

 in the Færoes, Rostrup writes: — »Specimens have been sent to 

 us by Mr. Randropp of Thorshavn«. And in Rostrup's collec- 

 tion of Færoese algæ there are some good examples of this species,
