6 SHALLOW-WATER FORAMINIFERA OF TORTUGAS REGION. 



and Caribbean are very inadequately known. Except for d'Orbigny's 

 classic work on the Foraminifera of the shore sands of Cuba and 

 other West Indian Islands/ published in 1839, little has been pub- 

 lished. Flint* in 1900 published on a few shallow-water samples 

 from off Porto Rico. I have just pubhshed a paper on the 

 Foraminifera obtained in a few samples from the north coast of 

 Jamaica,' and a few short lists are given in Publication 213 of the 

 Carnegie Institution of Washington, published in 1918. The 

 present collection, therefore, is useful in giving information for a 

 little-known region and the results have been interesting. Several 

 genera are here recorded for the first time from the Atlantic, and the 

 extension of ranges of others is considerable. A number of un- 

 described species were also obtained, as well as certain of the species 

 originally described by d'Orbigny from the West Indian region and 

 not since recorded. 



An extension of the present work to include the deeper-water 

 Foraminifera which occur in the adjacent region to the southward 

 would undoubtedly prove of interest in the determination of the 

 bathy metric ranges of many of the genera and species of the region. 

 This would be of much use in the interpretation of the faunas of 

 many of our Tertiary deposits of the Gulf Coastal Plain of the 

 United States.
