(B) Stage 2 testis. Note the thick layer of spermatogonia at the duct end of the testis (arrows). 156 X. (C) Stage 3 testis. The layer of spermatogenic tissue is thickened. The loops of germinal tissue underlain by hemal fluid in the hemal space are easily seen. 78 X. (D) Stage 4 testis. The spermatozoa do not form a separate mass in the lumen. 62 X. (E) Stage 5 testis, showing the separate mass of spermatozoa in the lumen. 7&X. (F) Section of ovaries just before spawning, showing the shape of the eggs and their small nuclei. Primary oocytes with swollen germinal vesicles can also be seen, and the degeneration of the follicle cells is evident. 78 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
