16. CELLEPORA. 



1. C. pumicosa, irregular, dirty white, rough, porous ; cells orbicular, the mouth round, 



with a produced marginal process. Pumice Cellepore.

 Cellepora spinosa, Turt. Br. Faun. 205. 

 Flustra bullata, Stew. Elem. ii. 436 ; Soland. Zooph. 16. 

 Hab. On sea-weeds and Zoophytes, common. 



Forms a cellular calcareous brittle mass, variable in size, and of no definite form. I have 

 seen young specimens of a purple colour. The aperture of the cells is often toothless, but 

 when perfect they have a blunt tooth-like process on the superior margin. 



2. C. ramulosa, dichotomously branched ; branches cylindrical, very slightly tapered, 



rough ; cells somewhat rowed, the superior margin of the aperture produced into a 

 blunt tooth. Little branched Cellepore (tab. nost. xii. fig. 3 and 4). 

 C. ramulosa, Flem. Brit. Anim. 532 ; Turt. Lin. iv. 640. 

 Hab. Attached to Corallines from deep water, frequent. 



The height of the largest specimen I have seen, and which is represented in our tab. xii. 

 f. 4, is about one and a half inch, but generally it is not more than the half of this. The 

 coralline is a pretty one, of a stony hardness, light, porous, and white. Ellis considered 

 it a variety of the preceding — Nat. Hist, of Zoophytes, p. 136. 



3. C. Skenei, much compressed, simple or slightly divided, rough ; cells in rows, oblong 



with a blunt tooth on the upper side of the round aperture. — Skene's Cellapore. 

 Millepora Skenei, Soland. Zooph. 135 ; Turt. Linn. iv. 635 ; Turt. Br. Faun. 204 ; Stew. 



Elem. ii. 427. 

 Hab. On Shells and Corallines from deep water, occasionally. 



Height about half an inch, breadth rather less, much compressed, with cells on both 

 sides, white, and when dry appears " as if covered over with a silver varnish." Ellis 

 suspected this was the " beginning of an elegant kind of Millepore ;" and Dr. Eleming 

 considers it to be Cellepora cervicornis in its earliest state. 



17. BERENICEA. 



1. B. coccinea, crust flesh, — red or purplish, sub-circular ; cells sub-cylindrical, frosted, the 

 aperture contracted, sinuated on the upper side, and armed above with a strong blunt 

 short tooth, (tab. nost. xii. fig. 5.) 

 Berenicea coccinea, Flem. Br. Anim. 533. 

 Cellepora coccinea, Lamour. Corall. 40.
