the fossil species. Having temporarily taken Mr. Barrett's 

 place in Jamaica, Mr. Wall, in conjunction with Dr. Dun- 

 can, communicated a very important notice of the geology 

 of that island to the Geological Society. That communica- 

 tion embodied descriptions and figures of many of the fossil 

 corals of Jamaica. 



The remains collected by Mr. Barrett in Jamaica having 

 been deposited in the British Museum, were examined 

 by Mr. Carrick Moore, who communicated in 1863 a notice 

 of them to the Geological Society. In 1865, being then in 

 London, I undertook at the request of Mr. Woodward the 

 description of these fossils, for which I had been prepared 

 by several years study of the fossils and recent shells of the 

 West-Indies, and at the same time I described and enume- 

 rated other fossil molluska and echinoderms from the West- 

 Indies, including Trinidad. Subsequently I communicated 

 to the Geological Society a resume of what was known of 

 the geology and paleontology of the tertiary formations of 

 the West Indies, enumerating the fossils and describing- 

 such new species as were accessible to me.* 



It will of course be understood that the present paper 

 relates to the tertiary geology only of Trinidad and the 

 Caribean area. But by way of parenthesis I may allune to 

 the secondary rocks of Trinidad, the conclusions as to 

 which have been based upon the researches of Boussingault, 

 Rcemer, Karsten, Lea, Von Buch, d'Orbigny, &c. On this 

 subject I have published a paper in the "Geologist." The 

 crectaceous rocks of Jamaica have been treated of by Barrett 

 and Woodward, and the latter has described from that 



* This paper contains references to most of the published works on 

 West-Indian Geology, and to it therefore I would refer those desirous 

 of working at the subject. It was published in the 22nd vol. of the 

 Quarterly Journal of she Geological Society. London 1866.
