Tadpoles of B. melanostictus and R. cyanophlyctis were reared in vitamin A solution. Rearing of the tadpoles of B. melanostictus in solutions containing 15, 20 and 30 IU/ml vitamin A palmitate resulted in complete disappearance of the keratinized epidermal material over the jaws and horny labial teeth. However tadpoles of the frog R. cyanophlyctis, were not affected in this way.
