Original Description

"Test long, compressed bilaterally, slowly becoming broader toward the apertural end; initial end bluntly compressed, while the apertural end is obliquely cut off. At the apertural end the rows of chambers are much shifted with respect to one another. Chambers spherical, alternating in two rows, forming moderate zigzags along the depressed spiral suture. Often the initial end of the test is planispiral. Chambers gradually increase in size toward the apertural end. Septal sutures depressed, slightly curved. Aperture semilunate, placed somewhat further on relative to the frontal plane of the second row of chambers. Wall calcareous, rows of pores are observed on the surface. Along the length of the test the number of pores in each row on the chambers exceeds 3 to 5. "
