Variety differing from the typical in its somewhat larger size and 

 in the presence of a stout, basal spine. Length, 0.40-0.72 mm.; 

 diameter, 0.24-0.38 nmi. 



The types are from the Oligocene, Grices Creek, Balcombe Bay, 

 Kackeraboite Creek, and Altoona Bay Coal Shaft, Victoria, Australia, 

 The variety also occurs in the Oligocene, Byram marl, Byram, Miss., 

 and the Miocene and Recent of Australia, and in the Recent of the 

 Fiji and Samoan Islands. In our material it has occurred at one 

 Albatross station, H3931, Anu Anuraro Atoll, % mile southeast, in 

 405 fathoms at 42.5° F., co.s.pter.oz.mang.part., as a smgle specimen. 

 A number of specimens were found in the material dredged at 40-50 

 fathoms off Fiji; a few at Mokaujar Anchorage, Fiji; and single speci- 

 mens from Makemo Lagoon and Pinaki Atoll in the Paumotu Islands. 



This variety has been given a new name owing to the priority of 

 Egger's Bulimina ovata d'Orbigny var. apiculata (1895). 



There is a great variation in size. The Recent specimens are 

 especially large and bear a close resemblance to Buliminella spinigera 

 Cushman. They differ, however, in lacking the high polish of the 

 latter, in having more numerous, more distinct chambers, and a less 

 regular shape.
