The fine structure of the corpuscle of STANNIUS in goldfish was examined with electron microscope and the following results were obtained. The cells of this organ contain many secretory granules with a limiting membrane. These granules are osmiophilic, round in form, and about 300 to 1000 mμ in diameter. Well developed rough-surfaced endoplasmic reticulum is observed within the cells. Two types of cells can be distinguished by the distribution of secretary granules and endoplasmic reticulum within the cytoplasm. They seem to be due to the difference in functional state of the same cells. The mitochondria of this organ are of cristae type. Free ribosomes and GOLGI apparatus are recognized. From the results obtained above, discussion was made on the nature of hormone secretion from the corpuscle of STANNIUS in teleost.
