Stem erect, compound, much and irregularly branched. 

 HydrotJiecce large, campanulate, with a plain circular margin, 

 borne on ringed pedicels (about three rings), and somewhat 

 spirally disposed. Gonothecce unknown. 



The calycles of this handsome species are distinguished 

 from those of all the other members of the genus by their size 

 and campanulate form. As I have already mentioned, they 

 are about three times as large as those of L. dumosa, and are 

 raised on a well-developed pedicel with three or four strongly 

 marked annulations. Instead of being tubular, they are of a 

 tall bell-shaped figure, expanding slightly towards the orifice. 

 They occur in pairs, which spring alternately from different 

 aspects of the stem, and assume therefore a somewhat spiral 

 arrangement. 



Though very abundant, L. grandis only occurs in fragments 

 amongst the Icelandic dredgings ; but Sars's figure* shows that 

 it attains a luxuriant shrubby growth, rising to a height of 

 about an inch and a half.

 Campamdaria gracillima, Alder. 



I have given my reasons elsewliere for identifying the 

 L. fruticosa of Sars with Alder's C. gracillima, notwithstanding 

 the opposite decision of G. O. Sars f. In one of the plates 

 which accompany this paper I have given figures, carefully 

 drawn with the camera lucida, of the Norwegian and the 

 British forms for comparison. Both the variety with a twisted 

 pedicle, described by Alder as C. gracillima, and the normal 

 L. fruticosa occur amongst the Icelandic dredgings. 



Calycella syringa, Linn. 



Abundant on other zoophytes. 



The calycles about double the size they attain in British 

 examples. The gonotliec^ are borne plentifully on the Ice- 

 landic specimens, and on others which I have received from 

 Labrador. They are comparatively rare on our coasts.
