dance near the ballast-pond at Torpoint, since which time this 

 variety of the plant has entirely disappeared. 



In the same year, the Eev. Mr. Hore and myself found 

 several specimens of that very rare and curious plant, Carpo- 

 mitra Cdbrerce^ washed up on the shores of Mount Edgecumbe. 

 Singular to relate, an interval of sixteen years had elapsed, and 

 not a single specimen, save these, had been taken since the solitary 

 one that was found by Miss Ball on tbe south coast of Ireland ; 

 and as previously to that occurrence no other specimen had been 

 taken. Dr. Harvey has remarked, in his ' Phycologia Britannica,' 

 that " this interesting plant is not truly the growth of our own 

 shores, but has been wafted hither, as other European productions 

 sometimes are, by the influence of currents." This surmise, how- 

 ever, proved to be incorrect, as both Mr. Hore and myself, since 

 our first meeting with this plant, have on various occasions found 

 it washed up on the shore at Mount Edgecumbe, and also at Tor- 

 point. In the autumn, of the years 1856 and 1857, I succeeded 

 in dredging some very fine specimens, growing in seven fathoms 

 of water in Plymouth Sound. 



In the month of October 1847, I picked up my first specimen 

 of that very rare and interesting plant, Stenogramme interrupta^ 

 amongst rejectamenta on the shore of Bovisand, near Plymouth, 

 — a plant which had never before been taken in Great Britain, or 

 perhaps in Europe. In the year 1849, and at various periods 

 since, many other specimens have been found washed up on the 

 shore. Latterly, however, I have taken with the dredge fine spe- 

 cimens of this plant, all growing on stones in six or seven fathoms 

 of water. Some years after my first discovery of the Stenogramme, 

 it has been dredged by Mr. Isaac Carrol in Cork Harbour. Miss 

 Giffbrd has also found specimens washed on shore near Minehead 

 in Somersetshire; but those I have seen from that locality are 

 much broader in the fronds than those taken at Plymouth. 



Gigartina pistillata, also a rare species, had not been found 

 in Great Britain since the year 1829, when in 1851 it was re- 

 discovered by my friend Mr. Gilbert Sanders, of Dublin, growing at 

 Whitsand Bay, near Plymouth. I have since, on various occasions, 

 secured other specimens of this plant, and always in the same 

 locality, but I do not think any of them were so fine as those 

 which were taken by Mr. Sanders. 



"When out collecting with Dr. J. "W. Budd, of Plymouth, in the 

 month of June 1854, we found growing in an obscure place 

 amongst the rocks in Firestone Bay, Plymouth, which was only
