Between 1865 and 1881 several authors described 18 specimens of extra legged frogs from different localities of Northern Italy. These neglected papers show that polymely was considered quite common among the lower vertebrates. The presence of a significant number of adult frogs affected by severe malformation in a pollution free age suggests the importance of natural origin of polymely.

Abstract
Between 1865 and 1881 several authors described 18 specimens of extra legged frogs from different localities of Northern Italy. These neglected papers show that polymely was considered quite common among the lower vertebrates. The presence of a significant number of adult frogs affected by severe malformation in a pollution free age suggests the importance of natural origin of polymely. The aim of this paper is to review the available bibliography on this subject, to remark that great caution should be given to link anuran malformations to the amphibians decline and to assess the causes of polymely.File in questo prodotto:
