GUPPY — TEPTIAUY FOSSILS OF THE WEST INDIES. 149 
fee 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 I860, 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 tho 
West-Indies, and at tho same time I described and enume- 
rated other fossil molluska and ecliinoderms from the West- 
Indies, including Trinidad. Subsequently I communicated 
to tho Geological Society a resume of what was known of 
the geology and paleontology of the tertiary formations of 
the West Indies, enumerating tho fossils and describing 
such new species as were accessible to me.* 
It will of course bo understood that the present paper 
relates to tho tertiary geology only of Trinidad and the 
Caribean area. But by way of parenthesis I may allude to 
the secondary rocks of Trinidad, the conclusions as to 
which have been based upon the researces of Boussingault, 
Boemer, Karsten, Lea, Yon Buch, d’Orbigny, &c. On this 
subject I have published a paper in the “ Geologist.” The 
cretaceous rocks of Jamaica have been treated of by Barrett 
and Woodward, and tho latter has described from that

West-Indian Geology, and to it therefore I would refer those desirous 
of working at the subject. It was pnblished in the 22nd vol, of the 
Quarterly Journal of the Geological Society, London 1866,
