In the foregoing list an interrogation mark (?) before the name of a 

 species means that the Eocene age of the species is questionable. Of 

 the 33 species listed, 10 are questioned and 2 of the unquestioned species 

 are not specifically identified, leaving 21. The undoubtedly Eocene 

 species are those from the St. Bartholomew limestone, St. Bartholo- 

 mew, and the San Fernando formation, Trinidad. At present only 

 species from these two formations may be used with assurance of 

 correctness in the identification of Eocene deposits, by means of 

 echinoids, in the West Indies and Central America. Eocene echinoids 

 have been found in Cuba and Jamaica, but their stratigraphic rela- . 

 tions are so imperfectly known that they can not be safely used for 

 correlation purposes.
