The test wall is calcareous, smooth and finely perforate. The test is planispiral, becoming rectilinear. The test is triangular in section, with a rounded outline. The apertural face is triangular and broad. There are approximately 4 to 5 visible chambers along the length of the test. The aperture is radiate at the dorsal angle of the final chamber.
