This species was truly magnificent when seen spread out in the 

 water, the disk expanding at least a foot in diameter, and densely 

 covered with large tentacles, tipt with bright lake ; the margin undu- 

 lating, so as to form numerous lobes, each of which had the appear- 

 ance of being a separate Actinia, and the whole resembling a beautiful 

 bouquet, J. P. COUTHOUY.
