 colour variety oi A. gemmacea. 



A. anguicoma, " The Snake-locked Anemone." —

 Coast') as an anguicoma that which I consider to be 

 a troglodytes. Undoubted specimens of troglodytes 

 have the vertical tentacle streaks which are given by 

 Johnston as characteristic of viduata. It is pro-

 unknown on the Devonshire coast. 



A. dianthus, "The Plumed Anemone." — Mr. W. 

 Thompson informs me that this is essentially a 

 deep-water species at Weymouth, and is never taken 

 in less than three fathoms water. Small specimens 

 have been forwarded to me by Mr. G. H. Lewes

 extreme low water. One small specimen lias been 

 discovered on Morte-stone, near Ilfracombe, by my 

 friend Mr. W. Brodrick. Mr. Thompson writes : —

 without injury to its base is a mistake ; they are not 

 more difficult to detach than are other species, and
