BUNODES CEASSICOENIS. PI. VI. fig. 2. 



This genus of Actinioid zoophytes is distinguished 

 from Actinia proper by the tubercles or warts which 

 stud the outer covering of the animal. In B. gem- 

 macea these warts are arranged symmetrically, so as 

 to give a peculiarly jewelled appearance to the body. 

 Being of a large size, the tentacles of B. crassicornis 

 exhibit in great perfection the adhesive powers pro- 

 duced by the nettling threads which proceed from 

 them. 



Caeyophyll^a Smithii. pi. VI. fig. 3. 



This figure is to show a whiter variety, with the 

 flesh and tentacles fully expanded.
