November and December, but none bearing cystocarps and anther- 

 idia, so tbe species doubtless bears fruit d uring tbe winter months 

 proper, as is also tbe case witb tbose growing along tbe Danisb 

 coasts. Kleen(l. c. p. 19) mentions, however, having found sporocarps 

 in June in Nordland. 



Lyngbj^e writes that the species is »Ad insulas Færoenses raro«, 

 and Rostrup says »Here and there«. I found it in several piaces in 

 exposed as well as fairly sheltered localities, so it may be recorded as 

 fairly common. 



Order RHIZOPHYLLIDACEAE. 

 POLYIDES Ag.

 Along tbe Færoese coasts it grows in the sublittoral zone; at 



any rate, I have not found it growing in the littoral zone in rock- 

 pools, as Kjell man says it does along the Norwegian coasts of 

 the Polar Sea. It generally grows on stony bottoms in deeper water 

 (some 10 fathoms), and is most commonly met with in sheltered 

 localities, but I have also gathered it from the open sea. 



It was found bearing tetraspores in April and October, and 

 young cystocarps in November. Kl een met with cystocarpic spe- 

 cimens in July in Nordland, and Kjell man gathered it in the 

 same month in Nova Zembla bearing both cystocarps and tetra- 

 spores. 



It appears to be fairly common along the Færoese coasts: — Str. :

 Bordo: Klaksvig (!), Aaerne (!); Vid: Kvannesund (H. J.); Syd.: Lobra (!), 

 Vaagfjord (H. J.), Trangisvaagfjord (Ostenfeld, H. J., !). 



Lyngbye may so far be said to have found this species in the 

 Færoes as there is a packet in his herbarium containing three small 

 pieces of alga, of which the two small ones are undoubtedly Polyides 

 rotundus. The packet is labelled in Lyngbye's handwriting »Furcellaria 

 rotunda?< In Hydrophyt. he does not record this species from the 

 Færoes.

This species occurs along tbe coasts of the Færoes both in the 

 lilloral zone and in the sublittoral. In the lilloral I most frequenlly
