Original Description

Disk with smooth surface, three times as broad as the medullary shell. Pores subregular roundish; nine to ten on the radius. Marginal spines fifty to sixty, cylindro-conical, flexuose, very variable in size, the largest nearly as long as the diameter of the disk. The spines lie not only in the equatorial plane (as usual), but also in two to four crowded girdles on both sides of it.

Diameter of the disk, 0.15, of the medullary shell 0.05; length of the radial spines 0.05 to 0.15, basal breadth 0.008. [dimensions in mm]
