Six species are thus undoubtedly represented in the present Ca- 

 ribbean Coral-fauna ; two species are not now found in the Caribbean 

 Sea, but exist in the Red Sea and Pacific Ocean ; and three species 

 arc found both in the Caribbean and the Pacific Coral-fauna?.

There are several species common to European and other strata 

 and the "West-Indian Miocene. 



1. Trochocyathus cornucopia;, il:fec^., sp Miocene of Tortoua, and 



Vienna basin. 



2. laterospinosus, Ed. ^ H. Miocene of Turin. 



3. obesus, Michelotti, sp Miocene of Tortona. 



4. Ceratotrochus duodecimcostatus, Croldf.^ sp. . Miocene of Turin and Albcrgo. 



5. Astrocoenia ornata, Mich. , sp Miocene of Turin, &c. 



6. Phyllocoenia sculpta, Mich., sp Lower Chalk of Martigues. 



7. Astrocoenia decaphylla, Mich., sp Lower Chalk of Gosau. 



8. Stylocoenia lobato-rotundata, Ed. ^ H. Miocene of Malta and Turin. 



9. Favoidea Junghuhni, Beuss Miocene of Java. 



10. Astr£ea crenulata, Gold/., si^ Miocene of Bohemia and 



Plaisance. 



1 1 . Stylophora raristeUa, Def., sp Miocene of Dax and Turin. 



12. Porites CoUegniana, Mich Miocene of Vienna and Turin^ 



The species common to the European Miocene, and the recent 

 Coral-fauna and the West-Indian Miocene being omitted, there 

 remains a fauna which is essentially characteristic of the West- 

 Indian Miocene. By comparing the genera of this fauna with those 

 of other faunae, some interesting results are obtained.
