Original Description
Liosphaerida with two cortical (extracapsular) shells (without a medullary or intracapsular shell).

Etymology: From the Greek liosphaera = smooth sphere

Extra details from original publication
The genus Liosphaera agrees with the preceding Carposphæra in the possession of two concentric latticed spheres; but whilst in the latter genus the inner sphere is a medullary one (intracapsular), the outer a cortical shell (extracapsular), both connected by radial beams piercing the capsule-wall, here in Liosphæra the central capsule lies freely within the inner lattice shell and is not pierced by radial beams. Therefore both shell, are here cortical shells, both separated by a distance, which is constantly much smaller than the radius of the inner shell; whereas in Carposphaera this distance is at least as large as that radius (commonly much larger). In Carposphaera the number of pores in both shells is never the same; in several species of Liosphaera this number is the same, each outer regular hexagonal pore exactly corresponding to an inner; the six corners of each connected by six short radial beams.
[Although Haeckel refers back to his Prodromus in 1881a, p.449, no mention of the genus Liosphaera is made there. Only the subfamily Liosphaeria is mentioned.]
