Original Description
Test free, inflated, low trochospiral, with broadly rounded periphery; chambers inflated, globular, increasing rapidly in size, early whorls with 4 to 5 chambers per whorl, rapidly reducing to 3 per whorl, which is most common in the adult; sutures distinct, depressed, radial; wall calcareous, finely perforate, surface finely spinose; primary aperture interiomarginal, umbilical, in the adult covered by a thin-walled umbilical plate which extends along the sutural depression over most of the umbilical side, and may even extend slightly onto the spiral side, outer margin of the umbilical plate with numerous accessory apertures which lie against the primary chambers and over the sutures as well, to open beneath the umbilical plate.

Size: Greatest diameter of holotype 0.35 mm, thickness 0.25 mm.

Etymology: The specific name is from the Latin ambitus, circumference + crena, notch, rounded projection. The name refers to the crenulated appearance of the border of the umbilical plate, caused by the accessory apertures.
