Original Description
Tholonida with double cortical shell (with external veil), with two hemispherical cupolas, opposite on the poles of one axis ; central chamber between them simple (without medullary shell).

The genus Tholodes (Pl. 10, fig. 2) differs from Thalartus, its probable ancestral form, only in the duplication of the shell; the outer shell has exactly the same three-jointed form as the inner; both are connected by eight radial beams, lying in two diagonal planes and corresponding to the eight frontal spines of Tetrapyle octacantha. Possibly Tholodes may also be descended from Amphitholonium by loss of the medullary shell. I have observed only one single specimen of this genus.

Etymology: Greek tholodes = cupola-shaped"
