TROPICAL PACIFIC FORAMINIFERA OF "ALBATROSS" 59 



This cosmopolitan species is represented only by scarce individuals 

 at a few stations. The specimens have 4 chambers per final whorl, 

 and the chambers are nearly globular in shape with little increase in 

 size as added. The sutures are indented and the periphery lobulate. 

 The aperture is rather wide, opening into the umbilicus, often with 

 the apertures of previous chambers still visible within the umbilicus. 



Rare specimens of Globigerina hexagona Natland are similar to 

 G. bulloides and can be confused with it, but they are separable on 

 the basis of a coarsely cancellate waD surface.
