Original Description
Test wall microperforate, pores randomly scattered and averaging 0.9 mm in diameter, wall surface smooth. Test small, very low trochospiral, equatorial periphery rounded, weakly lobate in equatorial outline; chambers subglobular, increasing slowly in size, ultimate: penultimate chamber ratio averaging 1.05, dextrally or sinistrally coiled in 2 whorls with 6.5 to 7 chambers in the final whorl; sutures moderately depressed in last several chambers, weakly depressed to flush on earlier chambers, radial on umbilical and spiral sides; umbilicus shallow, comprising 26 to 30% of the test diameter; aperture an extraumbilical low arch that extends from near the equatorial peripheral margin nearly to the umbilicus, bordered by a narrow lip, with relict apertural lips surrounding the umbilicus.
