conglomerate, the other a grey calcareous sandstone which often 

 consists of little else than comminuted shells. The grains of 

 sand found in varying proportions are fine and of uniform size

indicating deposit in tranquil waters of moderate depth. There 

 are many minute black specks which are probably manganese 



To show the distribution of these fossils, I have appended 

 a table showing the occurrence of the species elsewhere. The 

 presence of characteristic species of the Haitian Miocene indi- 

 cates that the deposit belongs to that period. Though Dall and 

 others have used the term " Oligocene " for the deposits of this 

 age I see no reason for doing so as the epithet Miocene is suffi- 

 ciently good for the typical series of deposits found in Haiti, 

 Jamaica, Cuba, Trinidad, Cumana, Panama, &c , &c. (See my 

 paper on the Caribean Region, Trans. Can. Inst. 1908 9, p. 381 ) 

 Most of the species dealt with in this paper are well-known to me 

 as occurring in the Caroni beds of Savancta. Many of them 

 were procured for me by my excellent friend, the late Louis 

 Alexander Leroy, a planter and colonist of high intelligence and 

 attainments. These I described and published in scientific 

 journals. For the naming of the present collection, I have 

 referred chiefly to the works of Carrick Moore and Sowerby on 

 the Haitian fossils, and to my own writings on the Jamaican, 

 Haitian and Trinidadian fossils I have also referred to Gabb's 

 work where necessary, and in a few cases to Call's fine monograph 

 on the Florida fossils. 



Some time ago, I published a Note on Fossils from Tamana. 

 As these affe of the same geological age as the present collection 

 and as the corals of the Tamana deposit are similar to those of 

 St. Croix, Xaparima, I take this opportunity to correct an error 

 made by P. Martin Duncan in his paper on these corals.* His 

 statements as to the alliances of the Naparima fossils and rocks 

 are incorrect. The St. Croix beds and the Tamana beds are
