1. Neurosecretory elements within the supramedullary nerve cells of the puffer, Spheroides niphobles, were stained by two staining methods: Gomori-Halmi's paraldehyde fuchsin (AF) and Gomori-Bargmann's chrome-alumhaematoxylin-phloxin (CH-P) (Enami, 1957, Imai, 1957). 2. Sections stained with the AF method did not show any definite stained granules within the cells. 3. Staining with the CH-P method showed numerous chrome-haematoxylin positive granules within the cytoplasm. These granules occasionally formed large colloids within the peripheral region of the cells (Fig. s.3-6). 4. Granules were also found in the axon originating from the cell (Fig. 2), but the site of the axon terminations has not yet been determined. 5. Detection of the stainable granules was made on specimens collected from March to July (1960). The chrome-haematoxylin positive granules were the most visible in the specimens collected in July. The activity of the cells appeared to be seasonal. 6. The supramedullary nerve cells of the puffer were surrounded by many blood vessels. In some cases, blood capillary penetrating into the cytoplasm was observed. 7. From these results it may be assumed that supramedullary nerve cells of the puffer have a secretory function.
