. Microsphere very small, eccentrical, with 8- 10 wide polygonal pores interconnected to outer medullary shell through 8-10 very thin beams of various length depending of their position in shell. Outer medullary shell spherical, rather thin and latticed with polygonally framed circular pores. Intervening bars thin, triangular in transverse section. Cortical shell spherical, rather thin-walled with numerous circular pores. Intervening bars thin with sharp crests and short and thin by-spines at vertices. Cortical shell bears 8-10 needle shaped spines about as long as skeleton ray. These spines are originated either in the microsphere or in the wall of the outer medullary shell, no one in the cortical shell.
