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


Plate 3. Collozoida.
Diam.
Fig. 1. Collozoum serpentinum, n sp (vel Collophidium serpentinum, Hkl), × 10
A living cœnobium, with expanded pseudopodia. The spherical calymma (or the common jelly-mass of the colony) is alveolate and contains numerous cylindrical, serpentine, central capsules. Numerous yellow cells or xanthellæ are scattered between the radial pseudopodia in the periphery.
Fig. 2. Collozoum serpentinum, n. sp., × 50
An isolated, cylindrical, worm-shaped, central capsule, with an axial series of oil-globules; the red points are nuclei.
Fig. 3. Collozoum serpentinum, n. sp., × 150
An isolated, cylindrical, serpentine, central capsule. k, Oil-globules forming an axial series; n, densely placed, red-coloured nuclei;, c, the capsule membrane under which are scattered small black pigment spots in the colourless cortical zone of the endoplasm; a, extracapsular alveoles; x, xanthellæ or "yellow cells."
Fig. 4. Collozoum amœboides, n. sp., × 100
A spherical cœnobium or jelly-colony. Each amœboid central capsule contains an oil-globule; the small red points are nuclei.
Fig. 5. Collozoum amœboides, n. sp., × 400
c, A single isolated central capsule; n, nuclei; k, oil-globule.
Fig. 6. Collozoum vermiforme, n. sp., × 30
g, A spherical cœnobium or jelly-colony; a, large alveoles, forming a cortical zone; c, central capsules; k, oil-globules.
Fig. 7. Collozoum vermiforme, n. sp., × 100
c, A single isolated central capsule; x, xanthellæ surrounding this central capsule; k, oil-globules; n, nuclei.
Fig. 8. Collozoum ellipsoides, n. sp., × 2
A spherical colony; the red points are central capsules.
Fig. 9. Collozoum ellipsoides, n. sp., × 150
c, A single isolated central capsule; k, oil-globules; n, nuclei.
Fig. 10. Collozoum inerme, Hkl., × 2
An old, cylindrical, articulated cœnobium; the red points are centralcapsules.
Fig. 11. Collozoum inerme, Hkl., × 2
A young cylindrical cœnobium; the red points are central capsules.
Fig. 12. Collozoum inerme, Hkl., × 400
A piece of a young colony with eight small central capsules, without oil-globules. n, The central nucleus in different stages of division. Two capsules are also dividing. x, Xanthellæ in the jelly-like calymma (blue), which also contains numerous vacuoles.
