424 THE CORYNACTIS. 



near the perpendicular ; yet they are not naked, being 

 encrusted with Flustrce, Cellularim, Lepralice, C9'isi(e, 

 Sertularice, and S2)onges ; and the lower parts are 

 studded with the elegant Madrepore, CaryopJtyllia 

 Smithii. 



The over-arching roof of the hollow in question, — 

 it cannot be called a cave, — was studded over with 

 scores of what seemed a new Actinia, for as the tide 

 had left them dry, they were all in a contracted state, 

 and I had no opportunity of seeing the beautiful 

 clubbed form of their tentacles that distinguishes the 

 genus Corynactis. They were, however, much more 

 tender and soft than the Actiniae, so that, though T 

 had no difficulty in detaching them with the point of 

 my pocket-knife, their substance yielded so much that 

 I feared I was destroying them ; especially as under 

 the irritation they gave out an enormous quantity of 

 thick, tenacious white mucus, scarcely less consistent 

 than their own substance. 



They were of various colours, but all beautiful. I 

 will describe them, however, not as I imperfectly saw 

 them then, hanging from their native roof-tree, but as 

 I see them now before me, some five and twenty of 

 the finest that I selected for preservation, now comfort- 

 ably established in a saucer of sea-water. 



First as to form. When contracted they are com- 

 monly little flattish warts or sub-conical buttons, 

 much like Actiniae ; but sometimes one will greatly 

 elongate its figure, swelling at the extremity, somewhat 

 like a long fig. (Fig. 8.) Sometimes they are very 

 much depressed, the surface corrugated, and the out- 

 line irregularly lobed. (Fig. 9.)
