Original description: Shell consists of single sphere or doubtfully double (see pl.1, fig.9b, Nishimura, 1992), having many radial spines. Outer shell considerably small, thick-walled, seems to consist of double layers because of well-developed distinct ridges extending from the base of radial spines. Outer shell with numerous, small, circular pores with polygonal pore frames, and with about 12 radial spines that are quite stout, three bladed in section except for the base. These spines are branched distally in some well-preserved specimens (see pl.1, fig.9a, Nishimura, 1992).
