FOEAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 387 



large to be placed in the jar. The largest specimens fully equaled 

 those described by Brady, and it is therefore the largest of the living 

 foraminifera and only equaled in size by a few fossil species of 

 Lepidocj/clina. The test is very thin and fragile and easily becomes 

 broken in the dredging. 



It has occurred in large quantities at D5184, between Panay and 

 Negros, 565 fathoms (1,033 meters); D5356, North Balabac Strait, 

 58 fathoms (106 meters); and D5640, Buton Strait, 24 fathoms (44 

 meters) . It is evidently not a widely distributed species, and probably 

 represents one of those older types which are now only found living in 

 this particular region. 



At station D5179, Avhere the species was so abundant, there are 

 specimens which have a secondary portion, due to a secondary out- 

 growth from near the center, so the specimens become composed of 

 three almost equal portions, one of these, however, usually at a greater 

 angle, so that the original plane of the surface can be seen.

Specimens have occurred well scattered over the Archipelago 

 proper, east and west coasts of Luzon, northern and eastern Mindanao, 

 off Cebu and in Jolo Sea, depths ranging from 32 to 500 fathoms (59 

 to 914 meters), and bottom temperatures from 41.2° to 52,3° F". (5.1° 

 to 11.2° C). Outside the Archipelago specimens were obtained 

 from D5613 in 752 fathoms (1,375 meters). Gulf of Tomini, Celebes; 

 and D5668, in 901 fathoms (1,648 meters), Macassar Strait, bottom 

 temperature 38.2° F. (3.4° C).
