The test wall is calcareous, smooth and finely perforate. The test is planispiral, becoming rectilinear and is triangular in section, almost twice as long as wide. Ridges form along the test surface, ending in spines along margins and pointing away from the apertural end. Chambers enlarge toward the terminal end, with the terminal chamber being the largest. The initial end is slightly curved away from the apertural end. The apertural face is triangular and broad. The aperture is radiate at the dorsal angle of the final chamber.
