TROPICAL PACIFIC FORAMINIFERA OF "ALBATROSS' 



33 



This variety has a definite basal spine and an elongate neck with a 

 distinct expanded lip, and the surface ornamented with distinct 

 longitudinal costae. Such forms have been already recorded from 

 the Philippines and from the North Pacific. Our specimens are from 

 near Nairai, Fiji, in 12 to 24 fathoms, where it was very common. 

 Except for this region the only other specimen is a single one from 

 Albatross Station H3938, latitude 19° 22' S., longitude 145° 47' W., 

 in 2,322 fathoms.
