Abstract
Dr. Duncan'S researches on the Palæontology of the West Indies have so much enhanced the value of any fossils found in those islands, that I do not hesitate to make a few remarks on some Orbitoides contained in a piece of Antiguan ‘Chert’, given many years ago, by Dr. Nugent, to the Geological Society, and to which Mr. H. M. Jenkins, Assistant-Secretary G.S., some months since directed my attention; and also on some specimens of fossiliferous flint and limestone from Jamaica.
