TROPICAL PACIFIC FORAMINIFERA OF "ALBATROSS' 



35 



Test subglobular to pyriform, greatest breadth usually at the middle 

 or below, base rounded or occasionally ending in slight spinose pro- 

 jections of the costae; wall ornamented with a number of longitudinal, 

 strongly raised, thin costae, running from the base to near the aper- 

 tural end where they coalesce into a platelike area below the aperture. 

 Length, up to 0.35 mm; diameter, 0.27 mm. 



This is one of the commonest species in our material from the 

 South Pacific, all the specimens, however, coming from the deeper- 

 water samples dredged by the Albatross, data for which are given in 

 Table 21. The species is widely distributed in the present oceans 

 in deeper water.
