Limb regeneration was studied in 13 adult amphibian species in which regeneration had not previously been investigated. Limb regeneration was not exhibited by four anuran species: Pseudacris triseriata, Hyla squirilla, Hyla crucifer, and Bufo quercicus. Among the adult urodeles studied, normal regeneration was observed in five species: Ambystoma laterale, another Ambystoma jeffersonianum complex species, Eurycea bislineata, Plethodon cinereus, and Plethodon glutinosus. Limb regeneration was absent or heteromorphic in individuals of Siren intermedia and Ambystoma maculatum. Regeneration was not exhibited at all by adult Necturus maculosus, and Ambystoma tigrinum. The phylogenic distribution of limb regeneration capacity, in the 41 species of amphibians for which information is presently available, is reviewed and discussed.
