Original description: Skelet eine etwas unebene Gitterkugel, aus unregelmäfsigen polygonalen Maschen mit sehr feinen Zwischenbalken in der Art zusammengesetzt, dafs eine Anzahl Gruppen von je 4-8 kleineren Maschen nach einer bestimmten Ordnung zwischen gröfser maschigen Feldern vertheilt sind. Die kugelige Centralkapsel erfüllt fast den ganzen Innenraum der Gitterkugel und ist ganz mit grofsen Olkugeln und dazwischen blauen Pigmentkörnern und hellen Bläschen erfüllt.


Translated description: Skeleton as an irregular lattice sphere with irregular polygonal pores and very thin frames, some groups of 4-8 smaller pores being distributed in a definite order between areas with larger pores. The spherical central capsule occupies almost all the inner cavity of the lattice sphere and includes large oil inclusions interspersed with granules of blue pigments and clear droplets. (In German. Translation by J.P.C.)]
Remarks on original description: [Revised by Haeckel, 1887a, as a subgenus of Cenosphaera]
