All Figures from preparations of Paludicella Ehrenbergii. 
Fig. 10. Surface view of cuticula near the end of a branch at intervals, a being 
nearest the tip, and d farthest from it. The branch was stained in 
Erlich’s hematoxylin, the color being taken up by superficial cuticula 
only. x 320. 
Figs. 11, 12, 13. Cross sections of the cuticula taken at different distances from 
the tip, to show the stainable and non-stainable cuticule. Figure 11 
is from near the tip, Figure 13 farthest from it. >< 1000. 
Fig. 14. Longitudinal median (sagittal) section through the tip of a branch show- 
ing cells of tip and an early stage in the development of the polypide. 
x 410. 
Fig. 15. Cross section of branch showing origin of lateral bud. x 635. 
Fig. 16. Longitudinal section of body wall of branch through the point at which 
a lateral bud is originating. Polypide of ancestral branch is nearly 
adult. X 685. 
Fig. 17. Longitudinal section of body wall from near the tip through the Anlage 
of a lateral bud. X 410. 
Fig. 18. Cross section of branch showing histological conditions of Anlage of 
lateral bud. The polypide has reached a stage of development cor- 
responding to that of Figure 36, Plate IV. 1000. 
Fig. 19. Longitudinal section through body wall from the same branch as Figure 
17, but farther from the tip. Histological conditions are to be com- 
pared with those of Figure 17, which represents a less differentiated 
condition. 410. 
Fig. 20. Cross section of branch in which the polypide has reached a stage slightly 
younger than that of Figure 36. To show Anlage of two lateral buds 
with their cuboidal undifferentiated cells. X 410.
