PLATE 3. 



COLLOZOIDA. 



Fig. 1. Collozoum serpentinum, n. sp. (vel Collopliidium serpentinum, Hkl.), . 



A living ccenobium, 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 xanthellae are scattered between the radial 

 pseudopodia in the periphery. 



Fig. 2. Collozoum serpentinum, n. sp., ...... 



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., ....... 



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, xanthellae or e ' yellow cells. " 



Fig. 4. Collozoum amceboides, n. sp., . 



A spherical coenobium or jelly-colony. Each amceboid central capsule contains an oil- 

 globule ; the small red points are nuclei. 



Fig. 5. Collozoum amceboides, n. sp., . 



c, A single isolated central capsule ; n, nuclei ; 1c, oil-globule. 



Fig. 6. Collozoum vermiforme, n. sp., ....... 



g, A spherical coenobium or jelly-colony ; a, large alveoles, forming a cortical zone ; c, central 

 capsules; Jc, oil-globules. 



Fig. 7. Collozoum vermiforme, n. sp., . 



c, A single isolated central capsule ; x, xanthellse surrounding this central capsule ; k, oil- 

 globules ; n, nuclei. 



Collozoum ellipsoides, n. sp., ....... 



A spherical colony ; the red points are central capsules. 



Collozoum ellipsoides, n. sp., 



c, A single isolated central capsule ; k, oil-globules ; n, nuclei. 



Collozoum inerme, Hkl., ...... 



An old, cylindrical, articulated ccenobium ; the red points are central capsules. 

 Collozoum inerme, HkL, ...... 



A young cylindrical coenobium ; the red points are central capsules. 

 Collozoum inerme, Hkl., ..... 



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, Xan- 

 thellae in the jelly-like calymma (blue), which also contains numerous vacuoles.
