Original description: Axoprumun with one single strong polar spine. Three shells subspherical tu cuboid; 20-25 pores on the equatorial plane. The medullary and cortical shells are joined by rods (about 6) disposed in the equatorial plane, and by 2 rods going to the opposite poles of the shell. One rod penetrates the cortical shell and forms a strong spine, three-edged and thorny at its end. The other rod projects as a small thorn. Secondary spines, three-edged, often broken, arise from the bars of the third shell.
