Original Description

Slightly convex skeleton with round or oval outline. Consists of frontal, sagittal and equatorial girdles, their wings connected to form regular round or oval rings. First system is of the ""Trizonium-type"" (in sensu Haeckel), its dimension = 30-40µm, with fully developed girdles; in the rest of them, only the equatorial girdle is fully developed; sagittal and frontal girdles terminate at the point of the junction with the ring of the previous system; distance between ‘width of rings) is considerably larger than the diameter of the central chamber. Soines (four main and four secondary) pass inside of the skeleton. Rim is smooth.

Etymology:
From the Greek circos = circle, and discos = disk.
