TROPICAL PACIFIC FORAMLNIFERA OF "ALBATROSS" 25 



main aperture is ventral and underneath the edge of the final chamber, 

 and both genera have what have been called supplementary apertures. 

 These are sealed over by shell material and appear as spirally elon- 

 gate bands just inside the perphery. In Mississippina these darkened 

 bands are present on both dorsal and ventral sides; in Stomatorbina 

 they are present only on the ventral side.

Described from the Paumotu Islands, this species is very rare. It 

 has also been reported from off Bikini and from the Pliocene Bodjong 

 beds in West Java. 



It is distinctive in having a series of openings on the ventral sur- 

 face, one to each chamber. The openings often are partially or 

 wholly sealed over.

Rare specimens occur in three of the shallow-water samples. They 

 are large for Foraminifera (up to 1.4 mm.) and strikingly beautiful. 

 The coarse and densely set pores in the otherwise nearly transparent 

 wall give a sparkling appearance to this species. It seems to have 

 been reported only from the Pacific.
