 amongst which they have hitherto been included.

 British Sea Anemones," by Gosse, Professor P. Martin Duncan

 Society of London, " On British Madrepora," in which he 

 enters fully into the history of the Caryophi/llm of the 

 British Seas, and at page 309, he says "that the specific 

 identity of the forms formerly called G. Smittii, of Stokes, 

 and G. horealis, of Fleming, is beyond doubt," and having 

 found that C. clavus of Sacchi has the priority, in future
