The list of species presents a remarkable assemblage of forms. The Caryophyllia are 
represented in existing seas, from low spring-tide level to 80 or 200 fathoms. The 
West Indian, the Mediterranean, the south-west and the north-east British seas, are 
favourite localities. With one exception, the Caryophyllia Smithi, they are always deep water 
forms; and this Coral is evidently a littoral variety of C. dorealis. The Oculimide of 
the present day are usually found under the same conditions as the Caryophylhe, and 
doubtless the Parasmilie and Trochosmilie were dwellers in from 10 to 200 fathoms.’ 
There are no forms which indicate shallow waters, or anything like a reef. The Coral 
fauna was a deep-sea one. 
1 Synonym, Cyathina levigata. 
2 Lower Chalk. 
3 Varieties or sub-species not hitherto described. 
4 Varieties or sub-species not hitherto described. 
5 See the remarks upon the propriety of absorbing P. Mantelli. M. de Fromentel has described 
Caryophyllia decemeris from Southfleet. Much experience in these species inclines me to believe that the 
decemeral arrangement is a monstrosity. There has only been one specimen of this species found. 
6 Lower Chalk. 
7 Dr. W. Carpenter, F.R.S., dredged up living Oculinide from the great depth of 530 fathoms, in the 
autumn of 1868.
