Original Description

"Large, loosely coiled, 4 chambers per coil, about 2 coils visible dorsally, ventrally nearly involute; spire flatly depressed, second coil more descending, chambers sub-globular, smooth, shining above and below but with faint peripheral sulcus margined by low nodules increasing in extent posteriorly to cover most of early chambers; umbilicus widely open, about one-third of shell diameter, aperture opening laterally into it, apertures of all ventral chambers probably visible if matrix absent. Size, 0.47 mm. Evidently a close relative of the abundant Navarro Globigerina rugosa Plummer, which has 5 chambers per coil and more ornament of a different character. It is a moot point whether these are not Globotruncana, as they differ only in the absence of keels and feebler sculpture"
