FORAMTNTFEEA OF NORTH PACIFIC OCEAN. 89 



This genus contains species such as Buliminella elegantissima 

 (d'Orbigny), where thespiral form of the test is very marked, and others 

 which show a lesser tendency toward the spire, such as Buliminella 

 subteres (H. B. Brady), B. declivis (Reuss) and B. contraria (Reuss). 

 It is very different from typical Bulimina, with its simple triserial 

 arrangement of the chambers.

Description. — " Test elongate-ovate, tapering to a blunt point at the 

 initial extremity, rounded at the distal end; consisting of from two to 

 three more or less regular, oblique 

 convolutions. Chambers relatively 

 large and only slightly ventricose ex- 

 ternally; sutural lines very distinct. 

 Aperture a curved slit near the in- 

 ferior umbilical margin of the termi- 

 nal chamber, considerably removed 

 from the distal end of the test." 



Length 0.4-0.6 mm. 



Distribution. — A single specimen 

 of this species was found in mate- 

 rial from Nero station 1254, in fig. 142. buliminella subteres. x so. 

 264 fathoms, south of Japan. It a ' APERTURAL view; b, side view. 



appears to be the only record for this region, although Brady records 

 it from eight stations in the South Pacific. 



The Nero specimen matched exactly the figure given by Brady and 

 reproduced here. The description is from Brady.
