Original Description
Test subglobular, more convex ventrally than dorsally; wall calcareous, finely perforate, completely covered with numerous fine papillae giving a granular appearance; periphery broadly rounded, slightly lobulate; all chambers exposed on dorsal side, only last whorl of five visible on ventral side; chambers inflated, increasing rapidly in size as added, last chamber extending slightly beyond previous ones, overhanging on ventral side to form a depressed umbilical area; dorsal sutures more or less distinct, nearly straight, slightly depressed; apertural face of last chamber flat, aperture a narrow slit extending from umbilicus about halfway along base of chamber toward periphery bordered on outer edge by a slight lip. 

Size: Maximum diameter 0.29 mm; minimum diameter 0.28 mm; maximum thickness 0.28 mm. "

Extra details from original publication
Remarks.- Probably the nearest relative to this small, compact species is Globigerina coalingensis Cushman & G. D. Hanna (1927), which is considerably larger and more ornamented over the dorsal chambers. The Lodo form has more chambers to the whorl and is flatter dorsally.

Range.-Samples I-X14 through I-S22+7.
