1 Some three years ago the late Dr. Karl P. Schmidt proposed to the Commission on Zoological Nomen- 

 clature that the name Siredon should be suppressed. He saw no reason to believe that the axolotl, Siredon 

 mexicanum, belonged to a different genus from Ambystoma. Until the Commission reaches a decision, the 

 axolotl is Siredon mexicanum, while mole salamanders are species oi Ambystoma.
