Bab. Lizard point, Polperro, Goran, Deadman point; 

 common on corallines and stones, from deep water. 



This, though a common, is not an abundant species. It is 

 calcareous, and while living; of a delicate flesh colour, which 

 afterward changes to a dull white. It arises from a spread- 

 ing base by a stout rough cylindrical trunk, and is di- 

 chotomously branched. The branches are short, stout, 

 cylindrical, very rough, and the terminal ones end in obtuse 

 points. The cells are numerous, urceolate, and in the young 

 state, appear to be qnincuncially arranged, but afterwards to 

 be without regular order. The apertures are contracted, 

 and armed with a long stout spine on the outer margin. It 

 varies in height from one to three inches. 



C. SKENEI. " Much compressed, divided in a bifid man- 

 ner, rough; cells rowed, with a strong macro on the outer 

 edge of the aperture." Skene.

Bab. On stones and the Pinna ingens, off the Deadman, 

 rare. 



This is a smaller and more compressed species than the 

 last and rarely exceeds half an inch in height. It is spa=- 

 ringly and dichotomously branched ; the branches are short, 

 palmate, and truncated. The cells are urceolate, rather 

 immersed, except in the newest parts, and somewhat 

 spirally arranged ; the apertures are slightly oval, but are 

 in a great measure hid by a strong stout spine on the outer 

 lip. This shape and arrangement of the cells give them a 

 resemblance to a fir cone, in which the scales are loosely 

 arranged. 



STAG'S-HORN CORAL. C. Cervicornis. Polypidom

 arranged.
