FORAMINIFERA OF THE ATLANTIC OCEAN 115 



Brady says that this species "is essentially a deep-water Foram- 

 inifer, and there is no reason to suppose that it is, under any 

 circumstances, a pelagic species." It is noteworthy, however, that it 

 usually occurs in Globigerina-ooze associated with pelagic species, 

 and the same is true of the fossil occurrences. 



There are other species in the Pacific which connect this with 

 typical Cibicides and other genera of the Anomalinidae.

 Truncaiulina (part) of Authors. 



Genoholotype. — Truncaiulina rostrata H. B. Brady. 



Test in the early stages trochoid, in the adult nearly planispiral and 

 with the chambers almost entirely involute; wall calcareous, coarsely 

 perforate; aperture on the ventral margin of the last-formed chamber 

 between the periphery and the umbilical area with a supplementary 

 aperture just below the peripheral margin, elongate and parallel to 

 the axis of coiling. 



Miocene (?) to Recent. 



This genus seems to be limited to the Indo-Pacific. 



Subfamily 2. Cibicidinae 



Test with the dorsal side flattened or concave, the aperture extend- 

 ing over onto the dorsal side along the inner margin of the chamber or 

 entirely on the dorsal side, test typically attached by the dorsal side.
