Abstract
Summary
1. A comparison was made between regenerating tail-tips in normal and hypophysectomized Rana pipiens tadpoles. 2. No significant differences were noted in amount of regeneration/unit time or in the histology of regenerates. 3. Age of the hypophysectomized animal had no discernible effect on tail-tip regeneration. 4. Independence of pituitary influence in regeneration exhibited by the anuran tail and Triturus retina-iris-lens system is discussed in relation to the dependence of limb regeneration in Triturus.
