Current identification: Cyphantella circopora

Original Description
Cortical shell thick walled, with smooth surface; pores subregular, circular, twice as broad as the bars; eighteen to twenty on the half meridian, twelve to fourteen on the half equator. Medullary shell spherical, its diameter one-half of the equatorial axis of the cortical shell. (The shell of this species is very similar to that of Cannartiscus amphiconiscus, Pl. 39, fig. 19, but without the polar tubes of that species.)

Size: Main axis of the cortical shell 0.13, equatorial axis 0.08; meshes 0.007, bars 0.003; diameter of the medullary shell 0.04.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Cyphanta circopora under the subgeneric name Cyphantella, but did not include the subgeneric name in the species name.[comment from RadWorld database]
