Bunodes Crassicornis. Pl. 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. gemmacea 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 produced by the nettling threads which proceed from them.
