Abstract

That "the Proteidae constitute the most primitive of the Urodeles" (Holmes, 1906) is generally accepted as an established fact. But here and there one finds dissenting opinions from this particular view. Kingsbury (1905) has given some very instructive and suggestive comparisons, chiefly of skeletal features, between Necturus and typical Urodela showing that Necturus and the larval stages of Spelerpes have so many characters in common that the similarities must stand for some degree of close relationship.
