Description. Test medium sized, globigerine, coiled in a very low trochospire ; 

 dorsal side inflated with the initial whorls slightly raised ; ventral side strongly 

 inflated ; equatorial periphery nearly ovoid and distinctly lobate ; axial periphery 

 broadly rounded ; chambers 15, arranged in 3 dextrally coiled whorls ; the initial 

 chambers are very small, inflated, globigerine and increase very slowly in size ; the 

 last whorl is composed of 4! large, globular, strongly inflated chambers, which increase 

 so rapidly in size that the penultimate and last chambers constitute most of the test ; 

 on the ventral side the chambers are 4^, large, globular, strongly inflated and increase 

 rapidly in size ; sutures on the dorsal side curved, depressed in the early part, nearly 

 straight, radial and depressed later ; on the ventral side the sutures are radial and 

 strongly depressed ; umbilicus irregular in outline, narrow, deep and open ; aperture 

 interiomarginal, extraumbilical-umbilical, in the form of a large rounded opening
