A few specimens from the Albatross station D5465, east coast of 

 Luzon, in 500 fathoms (914 meters), probably represent this variety 

 described by Heron-Allen and Earland from the Kerijnba Archi- 

 pelago.

Specimens are rare in the Philippine material, due perhaps to the 



comparative coarseness of many of the available samples. 



It has occurred rarely in the following localities: Siilu Archipelago, 

 off Jolo, off Tawi Tawi; two stations off Komblon; and the Pacific 

 Ocean, off the east coast of Mindanao. 



These stations range in depth from 23 to 249 fathoms (42 to 458 

 meters). 



It is recorded from the Malay Archipelago by Millett, and from the 

 Kerimba Archipelago by Heron-Allen and Earland. All but one of 

 Brady's records are from the Indo-Pacific. 



Heron-Allen and Earland figure specimens which, although larger 

 than the spiroloculine form, do not show that stage, and suggest that 

 these may be the microspheric form, which, growing larger, does not 

 show the adult characters.
