Original description: Shell is composed of two concentric lattice-spheres, a macrosphere and a cortical sphere. The macrosphere is thin-walled, 80 to 90 in diameter, with polygonal pores irregularly arranged and separated by slender intervening bars. One or more inner wands may sometimes extend centripetally without reaching the center. Cortical shell is thick-walled. It is connected with the macrosphere by forty, fifty or more thin radial beams that extend beyond the cortical shell as stout, cylindrical, or three-bladed spines of variable length and usually with their distal ends irregularly ramified. Their length, aspect in cross section (circular or three-bladed), and type of distal ramifications while varying with specimens are similar in the same specimen. The cortical shell has quite irregular pores, in size, shape and arrangement. Pores are seldom simple, they are often complicated by centripetal ingrowths from the pore-walls, which end by dividing them into two or more secondary pores (Plate 18, Figure 9).
