No. 3] REMARKS ON NORTHERN LITHOTHAMNIA. 95 



recorded below, whereas f. testacea is known only from Bergsfjord

 only from the latter place.

J ) A stunted specimen from Eyrarbakki (no. 486) referred by me to Ph. 

 compactum is rather approaching Lithoph. orbiculatum. The conceptacles 

 are small and feebly developed without sporangia, so that a certain deter- 

 mination is impossible. 



2 ) Owing to a slip of pen on my part, an error has slipped into Borg. Mar. 

 Alg. Faeroes p. 400. The form is recorded to have borne in the month 

 of June „ young sporangia" instead of young conceptacles. Therefore, the 

 determination of the only specimen known from that place is not quite 

 certain. Specimens faintly developed are hardly distinguishable from similar 

 ones of Lithoph. orbiculatum.
