Some Cretaceous and Eocene Corals from Jamaica. By 

 T. Wayland Vaughan. 



Introductory. 



Mr. Robert T. Hill has submitted to me for study the various fossil 

 corals that he has collected in his visits, made for Professor Alexander 

 Agassiz, to the West Indian Islands. The following paper has grown 

 out of a study of a part of this material, i. e. the so called Cretaceous 

 and the Eocene species. 



Duncan is the only author who has contributed to the paleontologic 

 literature on corals of these ages from Jamaica. His first paper, pub- 

 lished jointly with Wall, " A Notice of the Geology of Jamaica, espe- 

 cially with reference to the District of Clarendon ; with Descriptions of 

 the Cretaceous, Eocene, and Miocene Corals of the Island," ^ contains 

 notices or descriptions of the following '' Cretaceous " and Eocene 

 species : — 



Lower Cretaceous. 



Diploria crassolamellosa, Edwards Heliastrsea cyathiformis, sp. nov. 



and Haime. Cyathoseris haidingeri, Keuss. 



Heliastreea exsculpta, Reuss. Porites reussiana, sp. nov. 



Five species in all, three of which are identified with European species 

 and two described as new. As Duncan compares these species with the 

 Gosau favma, I took the opportunity while in Europe to visit the K. K. 

 Naturhistorischcs Hofmuseum in Vienna and study Reuss's types of the 

 Gosau corals.'^ Later I went to London and studied in the collection of 



1 Quart. Jour. Geol Soc. London, 1865, Vol. XXI. pp. 1-15. 



2 I am deeply indebted to Prof. Theodore Fuchs, Director of the Geological 

 Department of the Imperial Hofmuseum, and to Drs. Wahner and Kittl for giving 

 me every facility possible in my studies. Prof. E. Suess gave me access to all the 

 collections at the University of Vienna, and I express my hearty thanks to him.
