THE TRUMPET LUCERNAEIA. 217 



the pencil of Mrs. Johnston I had heen in the habit 

 of admiring, in her husband's admirable "History of 

 British Zoophytes." 



It was on the 3rd of October, that I detached, 

 at that sort of little natural pier that I have described 

 under the Nothe cliffs, a frond of Fucus serratus with 

 a bushy tuft of Rhodomela subfusca growing parasi- 

 tically on it. To one of the branchlets of the latter 

 plant a little mass of jelly was adhering, which, on my 

 dropping the branch into a phial of water, presently 

 expanded, and I had the pleasure of seeing the bell -like 

 form of Lucernaria auricula. It was a very young 

 specimen, not much more than one eighth of an inch 

 in height ; but I had got a clue to the search, and I 

 subsequently obtained through the month of October 

 many more. In spite of the gales and seas, I ma- 

 naged to drag up a good deal of the Fucus, which is 

 hereabout profusely fringed with Rhodomela, and 

 also with Ceramium ruhrum ; and on these, as also 

 occasionally on the Fucus itself, and once or twice on 

 Padina, I found the Lucemariae. 



My mode of examination was as follows. CoUectr 

 ing a basketful of the tufts at random, I brought them 

 home ; then one by one I waved them to and fro, in 

 the Tank of water, between my eye and the light, 

 whereby the animals became distinctly discernible, 

 and were easily detached. Sometimes four or five 

 were scattered over one tuft of the parasitic plant, 

 and it was rare to find a Rhodomela of any size, 

 without one at least. 



The specimens were evidently the young of the 

 season; many were no larger than I have named ; but
