Original Description: Test coiled in a moderate to high spire, equally to unequally biconvex, spiral side often more convex than umbilical side, average diameter of adult specimens 0.28 mm, average breadth 0.19 mm. Chambers globular, inflated, increasing moderately in size, three and three-quarters to four and one-half in the final adult whorl, four to four and one-half in the penultimate whorl, 10-12 comprising the tests of adult specimens, final chambers usually kummerform. Proloculus diameter averaging 0.017 mm, initial whorl diameter averaging o.07 mm, with a mean of 4.5 chambers in the initial whorl. Sutures radial and straight, strongly depressed on umbilical side, moderately depressed on spiral side. Aperture umbilical in position on adult specimens, usually obscured by a broad flap or thickened umbilical bulla. Apertures of juvenile specimens umbilical to extra-umbilical, having greater width than height. Surface distinctly ornamented with randomly situated, large pustules or high, narrow spines on adult specimens, smooth to finely pustulose on juveniles. Outer wall radial hyaline and finely perforate.
