Albatross station D 3603 in 1,771 fathoms in Bering Sea and D 4822 

 in 130 fathoms off Japan. It occurred at Nero stations 12 in 1,924 

 fathoms, 166 in 1,850 fathoms, and 189 in 1,813 fathoms between the 

 Hawaiian and Midway Islands and at a large number of Nero stations 

 between Guam and Japan at depths ranging from 1,321 to 2,250 

 fathoms. 



This species is easily distinguished from N. umbilicatula by its 

 much broader test in face view.

Nonionina depressula, var. orbicularis Madsen, Medd. Dansk. Geol. Forening, 

 No. 2, 1895, p. 217, pi., fig. 7. 



Description. — Test subglobular with ten or more chambers in the 

 final volution, in face view broad, periphery very broadly rounded, 

 almost flattened, umbilical region filled with shell material granular 

 as is also the material of the umbilical portion of the slightly limbate 

 sutures ; wall fairly smooth, the periphery lobulated slightly ; aperture 

 a narrow slit at the base of the apertural face of the chamber, the 

 lateral portions tending toward division by downwardly projecting 

 tooth-like portions. 



Diameter, 0.75-1.00 mm. 



Distribution. — The only record for this species in the North Pacific 

 is that of Bagg, Albatross station D 4566 in 572 fathoms off the 

 Hawaiian Islands.
