PLATE 11 
EXPLANATION OF FIGURES 
83 Giant spermatocyte in division. Note size of the cell and its follicle. 
84 A portion of large spermatocyte preparing for division. All such cells 
degenerate before completing the process. 
85 to 88 Large larval spermatocytes preparing for division. All degenerate 
before completing the process. 
89 and 90 Are isolated tetrads of larval germ cells in similar stages of devel- 
opment. Note variation in size of the tetrads in these cells. Figure 90 is from 
animal in second year. It is rare to find this type of tetrad in second-year larvae.
