Sea, off Hongkong and off Formosa; off northern Mindanao; Pala- 

 wan Passage; and Gulf of Tomini, Celebes. 



The peculiar dark condition of the material above the sutui'es was 

 noted in all the specimens. 



Specimens from Albatross station D5315 show excellent senescent 

 characters. The last-formed chambers of the test show a lateral 

 narrowing so that the width of this portion of the test is reduced to 

 one-half that of its maximum development. 



The type material of this variety was from Albatross station D4875, 

 in the eastern channel of the Korean Straits, in 59 fathoms (107 

 meters) .

Brady mentions that this variety is principally found under tropical 

 and subtropical conditions. It has occurred in the Philippine Expe- 

 dition dredgings from two stations in the China Sea, off southern 

 Luzon, D5105, 25 fathoms (46 meters), and D5300, in 265 fathoms 

 (485 meters) .
