TROPICAL PACIFIC FORAMINIFERA OF "ALBATROSS" 55 



Typical specimens are found in several of the shallower samples. 

 The species is characterized by its knobby top surface and the coarse 

 punctation of its wall. 



Genus PLANORBULINELLA Cushman, 1927 



PLANORBULINELLA LARVATA (Parker and Jones)

This is a form of Planorbulina acervalis in which the central part of 

 the dorsal side is broken up into small protruding knobs whereas the 

 peripheral part of the test retains normal-sized chambers. Only 

 three specimens were found. 



Genus ACERVULINA Schultze, 1854 



ACERVULINA INHAERENS Schultze

This attached species is characteristic of warm shallow waters. 

 A few typical specimens were found in several of the samples taken 

 near islands. 



As compared with Planorbulina acervalis, the wall of this species 

 is less coarsely punctate and the individual chambers are less individu- 

 ally inflated. On the other hand, the chambers appear to be irregu- 

 larly spreading outward over each other, and the top surface, con- 

 sequently, is smoother.
