Original Description
Sagittal ring thin, semicircular, smaller than the thin basal ring, which exhibits two semi-circular gates. Both rings are armed with numerous small spines of equal size, which on the former are arranged in two, on the latter in three regular rows. (The basal rod of the sagittal ring, separating the two basal gates, in fig. 3 is, by mistake, not distinctly enough drawn.)

Height of the sagittal ring 0.06, breadth 0.08.
