Catalog entries: Tribonosphaera centripetalis
type material: T. centripetalisOriginal description: Shell roundish or subspherical, with numerous small circular or roundish pores, about twice as broad as the bars. Twenty to thirty pores on the half meridian of the shell. Outside of the shell smooth, inside a variable number (ten to twenty) of thin, radial, centripetal sticks or spines, one third or one-half as long as the radius of the shell. (In the central capsule many very large crystals, resting after the destruction of the capsule.)
Diameter of the shell 0.1 to 0.12, of the pores 0.003 to 0.005, of the bridges 0.001 to 0.002; length of the inner centripetal sticks 0.02 to 0.03. [dimensions in mm]
