a subsequent paragraph. Pliocene corals from this locality are 

 considered on page 223. 



Mr. George C. Matson collected at Barranquilla, Colombia, some 

 fossils that belong to a fauna younger than that obtained around 

 Usiacuri, and may bo of Pliocene age. Glycymeris, Ostrea, Pecten, 

 and Lucina are the genera represented. 



The Bissex Hill "beds" of Barbados (see p. 583 of this paper) are 

 considered Pliocene in age by Franks and Harrison; but I infer, 

 from his remarks on the Foraminifera, that Chapman inclined to tho 

 opinion that they are of Miocene age. I strongly doubt any of tho 

 elevated, terraced coral reefs of Barbados being so old as Pliocene, 

 but present evidence is not decisive. Tho only known extensive 

 Pliocene coral fauna in America is that of the Waccamaw and 

 Caloosahatchee marls of the southeastern United States. This is 

 discussed on page 222 of this volume. I have studied both the 

 specimens on which Gregory based his account of the Barbadian 

 elevatcd-reef corals and a collection (see p. 255 of this volume) later 

 sent me by Professor Jukes-Browne. All of the species seem to mo 

 inseparable from the species at present living in the Caribbean area, 

 except one that was erroneously identified by Gregory as Lithophyllia 

 walli (Duncan). 



Pliocene deposits have been recognized at very few places in the 

 West Indies; in fact, about the only locality at which there is reason- 

 able surety of there being beds of this age is near Guantanamo, Cuba, 

 where Mr. O. E. Meinzer collected Pecten pittieri Dall, identified by 

 C. W. Cooke. 



R. T. Hill considers the Jamaican formations, to which he applies 

 the names Manchioneal and Kingston, as Pliocene, and it seems that 

 he is correct, but the evidence adduced is not completely convincing. 

 In other words, from the evidence available, Hill was justified in his 

 age classification of tho deposits mentioned, but their paleontology 

 needs more detailed investigation. 



The marine Pliocene of the southeastern United States has been 

 considered on page 576 of this paper. 



Heilprin was the first to call attention to the extensive Pliocene 

 "gray or white shell limestone" of Yucatan. 1 His examinations 

 were made "at several points in and about Merida, in numerous 

 cuttings along the line of tho Merida-Kalkini Railroad, on the line of 

 the railroad connecting the capital city with Ticul, all along the 

 traverse between Merida and Tunkas," and "at various points 

 between Tekanto and Cilam." Sapper has published a rough out-
