Summary The comparative fine structure of ultimobranchial (UB) glands of adult Israeli anurans (Bufo viridis, Rana ridibunda, Hyla arborea) taken in the wild during the breeding season is presented. Common aspects of the UB secretory cells are considered with especial reference to secretory granules, lipid droplets and tonofilaments. In B. viridis a second cell type with large electron-dense cytoplasmic granules is found in UB follicles. R. ridibunda and H. arborea UB follicles have a second cell type similar to goblet cells in appearance and these appear to be discharging their mucoid contents into the lumina of the follicles. The possible significance of these various cell types is considered.
