Scale line in A represents 100 /urn and applies to A, B, C, and E; scale in D represents 20 number continuously and exhibited many dark granular inclusions. By October, oocytes measuring 400-600 /xm in diameter had increased in number. The largest oocytes attained 800 /tin, with germinal vesicles of 200-/im diameter. A few de- generating oocytes were also found. Accessory cells, still empty looking, in- creased in number. The testicular acini of A. ijiinai are composed of an outer visceral peritoneum, a middle fibromuscular layer, and an inner layer consisting of germinal and non- germinal cells. The inner surface of the inner layer is covered with a thin con- nective tissue membrane, as in the 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. ).
