Extract

In his paper on “The Yellow Limestone of Jamaica and its Mollusca” (Geological Magazine, Vol. LX, 1923, p. 345) Dr. C. T. Trechmann referred to an Upper Senonian fauna from shales at Providence, near Port Antonio, underlying a limestone with Rudistae. He recorded Baculites from the upper portion of these shales, and “rather low in the sequence” he collected some ammonites, one of which had been identified by the writer as belonging to the genus Parapachydiscus. The Shales at Providence had already been mentioned by the late Mr. Lucas Barrett1 as containing Baculites and Hamites, and in his collection, now in the British Museum (Natural History), there are preserved a number of fossils including the Pholadomya and Trigonia he recorded and two fragments of Hamites. The matrix of these is the same as that of Dr. Trechmann's examples, namely a brown calcareous sandstone, and the ‘Hamites’ in both collections belong to the same species, but Mr. Lucas Barrett's Baculites I have not been able to trace.
