     It seems probable that this is a case of 'superregeneration'. As is well known, the tail of Plethodon is very easily detached. A study of the tissues of this tail gives evidence which, though not unquestionable, leads me to believe that it is relatively younger than the more anterior parts of the body. The experiments of Tornier ('97) and others in producing similar abnormalities by cutting off the tails of salamanders give added probability to this view.

     At the time Bateson’s book was written, however, little or nothing was known regarding the origin of supernumera y appendages in either the arthropods or the vertebrates. Since then a large amount of experimental evidence has accumulated to show that they may be formed by superregeneration, especially by regeneration from complex or irregular wound surfaces.

     Functional disturbances of the brain might give us the explanation here, just as material disturbances may serve to explain superregeneration in spite of all vitalism.
