FORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 319 



from near the Hawaiian Islands and off Japan at one station. In the 

 Phihppine material I have had the species from about a hundred 

 stations, mostly within the Archipelago, but it has also occurred in 

 the vicinity of Darvel Bay and Sibuko Bay, Borneo; Molucca Passage; 

 between Gillolo and Kayoa Islands; Buton Strait; and Gulf of Boni. 



The whole number of stations range in depth from 6 to 976 fathoms 

 (11 to 1,785 meters), with the average depth 238 fathoms (436 meters). 

 Bottom temperatures range, where given, from 40.1° to 76.3° F. (4.5° 

 to 24.6° C), with the average 52.7° F. (11.4° C). This is from about 

 half the stations, the bottom temperatures from the others, usually 

 the shallow-water ones, not being given; therefore the average is 

 probably much too low. 



At some of the stations specimens are very abundant and attain 

 a much larger size than in the colder waters. Some of the speci- 

 mens measured over 2 mm. in diameter. This is the most common 

 species of the genus in this area, and is evidently at home in warm, 

 comparatively shallow waters.

Brady records this species from 95 fathoms (174 meters) in ma- 

 terial dredged by the Challenger in the Philippines. Except for two 

 stations from the southern end of Japan these are the only North 

 Pacific records. 



It is interesting to note that the species has occurred frequently 

 in the Philippine region, but all the recorded stations are from the 

 Archipelago proper, except two stations off Darvel Bay, Borneo,
