✦ Synopsis

Small crenulated erythrocytes appear in the circulation of Rana pipiens during metamorphosis, increase in number as metamorphosis proceeds and gradually lose their wrinkled appearance. At the end of metamorphosis the entire red cell population has been replaced by these new cells. Thyroxine induces the premature appearance of these new cells in young tadpoles. 1 Supported by PHS grant HD00725-05 to A. G. Jacobson.
