First record. -Thompson, 1840; coll. Getty. 



Savigny gives " les mers d' Europe " as the habitat of 

 this species, it is presumed on the authority of Dr. 

 Leach from whom he received the specimen. Mr. 

 Thompson states that his specimens were not of so 

 lively a colour as represented in Savigny's work. No 

 specimens, however, are preserved in his collection. 



[This is probably the " Alcyonium rubrum, pulposum, 

 conicum plerumque' of Plancus (Bianchi) in 'Conch, 

 minus notis,' ed. 2 (1760), App., p. 113, pi. x.]
