DESCRIPTION OF PLATE III, 
Illustrating Professor Henfrey's paper on Chlorosplisera, a 
New Genus of Unicellular Freshwater Algae. 
rig. 
1. — Healthy plant, showing radiated cell-contents. 
2. — Cell in which division is about to take place. 
3. — A similar cell compressed, so as to separate the new cells. 
4. — A cell dividing naturally just before dehiscence. 
6. — A parent-cell about to dehisce, caused to split and discharge its progeny 
by pressure ; a, parent-cell ; by b, new ceUs. 
6. — A newly born cell burst by pressure, so as to show its delicate cell- wall. 
7. — A cell in which the contents have become broken up into green globu- 
lar corpuscles, perhaps the first stage leading to figs. 10, 11, 12. 
8. — Empty parent-cell, which has not completely separated into two parts ; 
the progeny escaped at a. 
9. — Another empty parent-cell, nearly in two parts; the progeny here 
escaped by longer slits. 
10. — A half of a parent-cell which has not discharged its contents, displays 
them converted into brown corpuscles. 
11, 12. — Cells in which the place of the contents is occupied by a central 
mass of flask-shaped bodies, which ultimately protrude their necks 
through the wall of the parent-cell, and seemingly open to discharge 
granular corpuscles. 
1 3, 14. — Cells in which the green colouring matter has disappeared, and the 
brownish contents which remain are accumulated at one side beneath 
a mass of urceolate bodies adhering to the outside of the cell-wall. 
These urceolate bodies open at their mouths and discharge minute 
corpuscles. 
15. — An ordinary cell, with brown contents. 
16. — A cell from specimens kept a long time in water, probably an unim- 
pregnated germ-cell in a diseased condition. The laminated secon- 
dary layers of gelatinous consistence are wanting at one part of the 
cell-wall. 
17. — Parent-cell imperfectly divided, one half containing a granular mass, 
the other a group of spores. 
18. 19. — Spores, solitary or grouped, apparently derived from cells like 
fig. 17. 
All X 200 diameters.
