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, indi- 

 cating 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, 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 Savaneta. Many of them were 

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

 Leroy, a planter and colonist of high intelligence and attain- 

 ments. 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 fos- 

 sils, and to my own writings on the Jamaican, Haitian and Trin- 

 idadian fossils. I have also referred to Gabb's work where neces- 

 sary, and in a few cases to Ball's fine monograph on the Florida 

 fossils. 



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

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

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

 St. Croix, Naparima, 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
