Catalog entries: Choenicosphaera flammabunda

Original description: Shell spherical, with circular or roundish pores of very different size. The smaller pores very numerous and unequal, very irregularly scattered, hardly one-fourth to one-half as broad as the bridges between them. Twelve to twenty-four pores in the half meridian of the shell. Between them, irregularly scattered, a variable number (ten to twenty) of very large circular pores, about one fourth as broad as the radius of the shell. The margin of these large pores is armed with a very irregular coronal of four to twelve unequal, curved acute spines, partly simple, partly branched like a deer-horn, one-fourth to one-half as long as the radius of the shell. Some other small spilles irregularly scattered over the shell.

Diameter of the shell 0.12 to 0.16, of the smaller pores 0.001 to 0.004, of the larger armed pores 0.016 to 0.024; length of the spines 0.02 to 0.04.
Remarks on original description: Haeckel listed Choenicosphaera flammabunda under the subgeneric name Choenicosphaerium, but did not include the subgeneric name in the species name.
Stratigraphic information for LM21 from Riedel, 1959, p.287.
