rORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 399 



from Funafuti. The material from western Australia Sidebottoni 

 definitely refers to Challenger figures 12 and 13. Millett gives no 

 figure and simply says: "A few small specimens from both areas" 

 (Malay Archipelago). 



With this more or less indefinite recording and the fact that the 

 specimens from a])out the British Isles do not seem related to the 

 Indo-Pacific material it would seem that there quite likely m.ay be 

 several species now going under this name. I would limit the name 

 to those specimens of the Indo-Pacific like figure 15 of the CliaUengtr 

 Report and possibly the figure 13, v/hich ma}'^ be an earlier stage of 

 the same. 



In the Philippine material it has occurred at but one station, D5242, 

 off Pujada Bay, in 191 fathoms (350 meters).

Desaiption. — Test much compressed, planospiral; chambers nu- 

 merous, usually more swollen toward the basal end, inflated, nearly 

 circular in transverse section, the apertural end somewhat produced^ 

 sm'face smooth; periphery of the test with a distinct, rather broad, 

 sharp, plate-like carina, in young specimens rather even, but in older 

 ones more or less irregular; chambers closely adjacent to one another, 

 not separated; apertural end with a slightly produced and slightly 

 fiaiing lip; aperture round. 



Length slightly less than 1 mm. 



This species, originally described from off Guam and off Japan, has 

 occmTed at two stations in the Philippine ai'ca — D5349, Palawan Pas- 

 sage, in 730 fathoms (1,335 meters), and D5445, east coast of Luzon, 

 in 383 fathoms (699 meters). 



Eggcr's figures of S. acutimargo suggest that they may be S. tenui- 

 margo.
