Summary

Granules in the adepidermal space of larvae of Salmo irideus, Hynobius tokyoensis and Rhacophorus buergeri, were observed by transmission and scanning electron microscopy. Adepidermal granules of S. irideus were smooth and spherical structures, those of H. tokyoensis were smooth and spherical, or oval, while in R. buergeri these granules appeared as single or grouped tangled strand-like or starfish-like structures under the scanning electron microscope. These adepidermal granules were spread all over the basal lamina in every animal investigated. The different sizes of adepidermal granules of S. irideus and H. tokyoensis seen under the transmission electron microscope are not the result of differently sectioned faces of granules, but the granules themselves exhibit different sizes. The probable functions of these granules are discussed.
