Collodictyon meets Pandorina and loses out. Escape of Pandorina and subsequent dissolution of Collodictyon due to drying. Diagrammatic. × 750. 1. Pandorina within food vacuole. 2. Pandorina swimming away; ruptured surface of Collodictyon. 3, 4. Apparent healing of torn surface. 5. Fusion of ends of protoplasmic processes, enclosing water vacuole; of frequent occurrence. 6-8. Resorption of protoplasmic processes. 8, 9. Flattening of body; formation of pathological vacuoles indicative of dissolution. 10. Bursting of vacuole at anterior region of sulcus. 11. Further dissolution, rupturing posteriad along the sulcus. 12. Nucleus and blepharoplast freed by dissolution, a. Nucleus; nuclear membrane persisted for two minutes. b. Rupture of nuclear membrane, c. Karyosome; persisted for thirty minutes; finally broke up into small granules, d. Blepharoplast; basal granules surrounded by archoplasm, flagella still moving, e. Rupturing of archoplasmic mass; flagella cease beating.
