Yery rare. round by Mr. Borrer on the beach at 

 Brighton. Miss Turner has kindly sent me a specimen of 

 it from Jersey. 



5. Griffithsia corallina, Agardh. 



Hab. On rocks at low-water mark, or in deep pools. 

 Annual. Summer. Very generally distributed. 



This is one of the most attractive of our Algae, and ac- 

 cordingly we find it noticed by our early botanists, — by 

 Linnaeus and Dillenius. Its fine red, glossy beads are de- 

 cidedly coralline-like. I suspect that it is not common in 

 Scotland ; but when I say so respecting any plant, I wish 

 it to be borne in mind that many of our richest localities 

 have not been very scrutinizingly explored; — much, for 

 instance, of the rich Carrick shores, in Ayrshire ; much of 

 Wigtonshire, about the Mull of Galloway, where my worthy 

 friend the Rev. Mr. Lamb allows no rare /^^^r/-plant to escape 

 his notice, but who has not yet kept so keen a look-out for 

 rare ^m-plants ; much also remains to be done about the 

 IMull of Kintyre in Argyleshire, at Macrihanish Bay, and 

 Dunaverty"^ Bay, perhaps the richest habitats in Scotland, 



* Dunaverty means the hill of slmighter, and the mournful passage of 

 history which gave rise to the name may be found in Sir W. Scott's ' Tales 

 of a Grandfather.'
