WeEnnicH.— Spermatogenesis of Phrynotettix magnus. 
PLATE 1. 
All figures are of the early spermatogonia. 
Figs. 1, 2— In metaphase. 
Figs. 3, 4.— In anaphase. In figure 4 the cytopldsm has been drawn in order 
to show the hyaline region around the chromosomes. 
Fig. 5.— Early telophase. 
Figs. 6, 7— Side view and optical section (polar view), respectively, of an 
early telophase in which the chromosomes have begun to expand. 
The cytoplasm has been represented in order to show the hyaline 
region around the chromosomes. 
Figs. 8, 9— Side view and optical section, respectively, of later telophase. 
Vesicles persistent. 
Figs. 10, 11— Side view and optical section, respectively, of late telophase. 
Vesicles mostly disappeared. 
Figs. 12, 13— Side view and optical section, respectively, of stage showing 
the greatest diffusion of chromatin that was found.
