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. |
