Original Description
[Translation from the Russian. - Test large for the genus, consisting of 3 whorls with 4 chambers in each whorl. Dorsal side in the form of a turret-like spiral which strongly projects upward; ventral side convex with the exception of a large umbilical portion which is depressed. Chambers spherical, loosely attached to each other. In the center of the ventral side there is a wide umbilical portion which is depressed. Chambers spherical, loosely attached to each other. In the center of the ventral side there is a wide umbilical depression which is formed due to the ringlike arrangement of chambers in the final whorl. The apertures of chambers in the final whorl open into this depression. Chambers of the various whorls differ considerably in size. Within one whorl, the chambers vary but little in dimensions. [In the majority of specimens which were studied, a bladder-like float has been noted. It is always smaller than the final whorl and looks like a tubercle from the outside. It is located in various positions, either in a different plane than all the chambers of the last whorl or in the same plane. This "float" makes the test look asymmetrical, It is always consideralby thinner-walled than the chambers and has no orifice or pores. If the "float" is removed by dissection, the test acquires the shape typical of the four-chambered Globigerinas. (A test with traces of such "float" is shown on plate 9, figure 6a-c.) [The aperture of each chamber looks like a short slit which is covered throughout its entire length by a large, thin, lamina-like lip. Usually the apertures are not visible because they are hidden by the curved face of the chamber. Wall pitted, coarsely porous. Dimensions: Diameter 0.45-0.55 mm.; thickness 0.30-0.36 mm.
