This series of memoirs, which has resulted from a minor grant made 

 by the Carnegie Institution, presents data for the correlation of the 

 different geologic events in the West Indies. The evidence furnished 

 by all the classes of organisms studied is in accord. It is expected 

 that this volume will be followed by others containing accounts of the 

 fossil corals, the echini, the fossil and living land mollusks, and the 

 stratigraphy and geologic history of the region. 



1. Five species of coralline algae are described: i from the Eocene 

 of St. Bartholomew, 3 from the Oligocene of Antigua, and i from the 

 Oligocene of Anguilla. 



2. The Foraminifera reported on are the Vaughan collection from 

 the Leeward Islands, the Maur>' collection from Santo Domingo, the 

 Johns Hopkins University collection from Bowden, Jamaica, and sev- 

 eral lots from Cuba. The correlations indicated by the Foraminifera 

 are discussed and 117 species are described or listed. 



3. The Bryozoa described number 42 species; three of them are re- 

 ferred to new genera. The collections studied include representatives 

 from the Oligocene of Antigua, Anguilla, and Panama and from the 

 lower Miocene of Jamaica, Santo Domingo, and Costa Rica. The 

 stratigraphic position and range of the species is tabulated. 



4. In addition to loi species of mollusks, including one new genus, 

 from the Eocene, Oligocene, and Miocene of St. Bartholomew, Antigua, 

 Anguilla, and Cuba, two new^ species of brachiopods from the Eocene 

 of St. Bartholomew are described. The correlations of the formations 

 are briefly discussed.
