Description
English: Illustration from Report on the Radiolaria collected by H.M.S. Challenger during the years 1873-1876. Part III. Original description follows:


Plate 4. Sphærozoida
Diam.
Fig. 1. Sphærozoum trigeminum, n. sp., × 50
An annular colony. The main mass of the jelly-colony is filled up by large alveoles; the entire surface is densely covered with spicula, and beyond this skeleton-cover lie the spherical central capsules, each with an oil-globule. This species is by mistake not mentioned in the text.
Fig. 2. Sphærozoum alveolatum, n. sp., × 50
Section through a spherical colony; displaying the inside of a hemisphere. All the central capsules lie in a single stratum on the surface of the jelly-sphere, each being surrounded by a thick-walled alveole. The spicula lie between the alveole and the capsule, which includes a central oil-globule.
Fig. 3. Sphærozoum alveolatum, n. sp., × 400
A single central capsule, filled up by crystal-spores. Numerous geminato-radiate spicula and spherical xanthellæ lie between the capsule and the including thick-walled alveole. In the jelly-calymma, between the capsule and the alveole, numerous thin ramified pseudopodia are expanded.
Fig. 4. Sphærozoum geminatum, n. sp., × 400
A single central capsule, with a central oil-globule, surrounded by numerous spicula and spherical xanthellæ. The jelly-substance of the calymma is expanded between the points of the spicula.
Fig. 5. Sphærozoum variabile, n. sp., × 300
Three isolated spicula.
Fig. 6. Sphærozoum pandora, n. sp. (vel Rhaphidozoum pandora), × 300
A group of various spicula.
Fig. 7. Sphærozoum verticillatum, n. sp., × 300
A single spiculum.
Fig. 8. Sphærozoum arborescens, n. sp., × 300
A single spiculum.
Fig. 9. Sphærozoum armatum, n. sp., × 300
A single spiculum.
