Original Description

Test inconspicuously trochoid; chambers distinct, greatly inflated, three to four in last whorl; sutures distinct, strongly depressed; wall coarsely perforate, glassy; aperture large, irregular with crenulated edges.  Cotype.

Size:
Diameter 0.61 to 0.45 mm., thickness 0.32 mm.

Etymology:

Extra details from original publication
This species is tentatively assigned to the genus Sphaeroidinella on the basis of the strongly punctate, glassy wall and irregular, crenulated edges of the aperture. It must be admitted, however, that in some respects the form is closely allied to Globigerina. It is quite possible that this species represents a more matured phase of Globigerina seminulina Schwager described from the "Pliocene" of Kar Nicobar. This species is commonly found in late Tertiary assemblages of the Indo-Pacific region.
