Test free, small, trochospiral, spiral side flattened, umbilical side strongly convex and highest at the umbilical shoulder around the small deep umbilicus, periphery subangular, peripheral outline only slightly lobidate; chambers low and relatively broad on the spiral side, with 6 or more rarely 7 in the final whorl, the chambers sloping sharply outward to the periphery from the umbilical shoulder at the small umbilicus,giving the test a low conical appearance; sutures distinct, curved obliquely backwards on the spiral side, radial on the umbilical side ; wall calcareous, finely perforate, entire surface may be hispid, but with early spire most prominently spinose, final one or two chambers may be somewhat more smooth; aperture a very small interiomarginal, extraumbilical-umbilical arch.
