Original Description

Cette espèce s'écarte bien peu de la précédente avec laquelle nous l'avons longtemps confondue. Nous pensions que les différences observées dans la coloration de la capsule centrale étaient en rapport soit avec la nature des proies ingérées, soit avec le stade évolutif du Protiste. En fait, C. ruber est une forme autonome que l'on distinguera essentiellement de C. mediterranensis à son tissu spongieux plus fort, ne formant jamais une coque régulièrement sphérique. Comme chez Spongosphaera streptacantha, les trabécules du tissu spongieux, d'égale épaisseur du centre à la périphérie du squelette, constituent autour des spicules des prolongements pyramidaux plus ou moins nettement indiqués. Dans leur portion libre, les spicules (de 16 à 30) portent de 6 à 7 verticilles d'épines.
[This species is very close to the former species [C. mediterranensis] with whom we confounded it during a long time. We thought that the differences in the coloration of the central capsule were due to the nature of the preys, or the growth stage. In fact, C. ruber is an autonomous form that is easily distinct from C. mediterranensis by a stronger spongious tissue never producing a regularly spherical shell. As in Spongosphaera streptacantha, the bars of the spongious tissue, of similar width from the center to the periphery, constitute around the radial beams some pyramidal protuberances, more or less pronounced. In their free parts, the radial beams (16 to 30) bear 6 to 7 verticils of spines. (In French. Translated by J.P.C.)]

Microsphere 20µm. Spongious shell 600µm. Meshes of the spongious shell approx. 30µm. bars 3µm. Interval between C1 and the spongious shell 30µm. Total length of radial beams 600µm. Free parts of radial beams 300µm. Central capsule in larger specimens wider than 500µm.
