PLATE VII. 
Sagittal section through posterior end of male, slightly lateral, showing 
large cells and processes in anal ganglion. Bohmer’s hematoxylin. 
1.C. X 180. 
Gregarinida from mass of spermatozoa. One in cross section is shown 
ata. Mayer’s HClcarmine. 3.D. X 660. 
Transverse section, slightly oblique, from near the tip of the head, show- 
ing sensory cells, and nerve fibres passing up towards them. Ehrlich’s 
hematoxylin. 2.C. X 230. 
Isolated sensory cells from front end of head. Ehrlich’s hematoxylin. 
Apochr. 4mm. Compens. Uc. 8. X 725. 
Diagrammatic representation of the relative size and position of the large 
ganglion cells in the brain. The extremes of variation in the position 
of the second pair (cl. gn. II.) are represented on the right and left of 
the figure. Dorsal aspect with the dorsal cells removed; the deep- 
lying cells appear fainter, cells which are nearer being more promi- 
nent. Drawing by A. G. Mayer. 
Oblique longitudinal section of posterior portion of the brain and the par- 
tition which cuts off the anterior chamber. The deepest and last 
portions of the processes of the dorsal cells are shown. Ehriich’s 
hematoxylin. Apochr.4 mm. Compens. Oc. 8. X 725.
