FOKAMINIFEEA OF THE PHILIPPINE AND ADJACENT SEAS. 369 



This is the most common species of the genus and one of the most 

 common of the foraminifora in the whole region. It is distinctively 

 characteristic of tropical shallow water and reaches exceptionally 

 fine development in this region. It occurred at 55 stations, ranging 

 in depth from 10 to 565 fathoms (18 to 1,038 meters), the average 

 depth 95 fathoms (174 meters). Bottom temperatures are given at 

 but 12 stations, ranging from 47.4° F. to 75.7° F. (8.5° C. to 24.2° 

 C), the average temperature 57.1° F. (13.9° C). 



It is much more abundant at the stations in depths of 25 fathoms 

 (46 meters) or less, and apparently is found in very shallow water.
