Polar tubes conical, about as long as one single chamber, on the base somewhat broader than the simple spherical medullary shell. Pores of the tubes only one-third as great as those of the chambers.

Main axis of the cortical shell (without tubes) 140µm, greatest breadth 100µm; pores 8µm, bars 4µm. Length of the polar tubes 70µm, basal breadth 40µm; pores 3µm, bars 2µm.
