Catalog entries: Thecosphaerella glebulenta

Original description: Double medullary shell connected to cortical shell by approximately 7-10 bars. At their points of junction with the cortical shell, the latter is as if drawn inward in relation to the other parts of the shell, which thus has an irregular, lumpy appearance. Cortical shell wall moderately thick, with pores tending to be rosette-shaped and surface greatly roughened by small thorns which are joined by lamellar extensions if the intervening bars. No external spines.
