English: Illustration from Report on the Radiolaria collected by Challenger during the years 1873-1876. Part III. Original description follows: Plate 5. Collosphærida. Diam. Fig. 1. Trypanosphæra transformata, n. sp., × 150 A living colony. The centre of the spherical cœnobium contains a large alveole, surrounded by a net of sarcode. The entire calymma is filled up by smaller, thin-walled alveoles. Its inner part contains numerous small, young, central capsules (each with an oil-globule) without shells; in the cortical zone of the calymma lie larger capsules, each of which is enclos

Trypanosphæra transformata, n. sp., × 150 A living colony. The centre of the spherical cœnobium contains a large alveole, surrounded by a net of sarcode. The entire calymma is filled up by smaller, thin-walled alveoles. Its inner part contains numerous small, young, central capsules (each with an oil-globule) without shells; in the cortical zone of the calymma lie larger capsules, each of which is enclosed by a fenestrated shell with from two to four or more dentated tubes. Between the radiant pseudopodia very numerous small yellow cells (xanthellæ), which are scattered everywhere. Fig. 2. Trypanosphæra transformata, n. sp., × 300 A single shell. Fig. 3. Trypanosphæra coronata, n. sp., × 300 Fig. 4. Trypanosphæra trepanata, n. sp., × 300 Fig. 5. Odontosphæra monodon, n. sp., × 300 Fig. 6. Odontosphæra cyrtodon, n. sp., × 300 Fig. 7. Acrosphæra inflata, n. sp., × 300 Fig. 8. Mazosphæra hippotis, n. sp., × 400 Fig. 9. Mazosphæra lagotis, n. sp., × 300 Fig. 10. Pharyngosphæra stomodæa, n. sp., × 400 Fig. 11. Buccinosphæra invaginata. n. sp., × 500 Each shell contains numerous larger and smaller crystals. Fig. 12. Tribonosphæra centripetalis, n. sp., × 500 Each shell contains numerous large crystals.
