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 published 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 
bathymetric 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.
