Original Description

Test with a flat or weakly inflated  spiral side and a convex umbilical side; umbilicus narrow, outer margin initially angular later rounded. There are two whorls, the last one with 5½ to 7 inflated chambers. Sutures depressed, arcuately curved on the spiral side, straight on the umbilical side. Aperture slitlike, opeing into the umibilcus, wall thin, cancellate hispid; spinosity coarsest at the umbilica ends of the chambers and at the periphery of the test. This species differs from Acarinina carinata Subbotina in the less compatct arrangement of the chambers and their greater number per whorl. This species is tranisitonal between the genera Globigerina and Acarinina and in all probabilty originated from Globigerina cretacea d'Orbigny.
