Abstract:
INTRODUCTION. In 1959 I started a series of experimental and descriptive studies concerning the external morphology as well as the anatomy, histology, and cytology of Bombina. Their purpose was to obtain more information on the degree of the evolutionary affinity between the two species of Bombina inhabiting Europe. The first portion of results concerning the problems of biometry of metamorphosed forms has been published under the somewhat different joint title (Studies on species characters in Bombina variegata (L.) and Bombina bombina (L.) Michałowski, 1961). The objective of the present work was 1) to analyse the most important taxonomic characters of Bombina tadpoles so far recorded in literature on my own material, 2) to try to find new characters, 3) to work out the taxonomic characters quantitatively as far as possible, 4) to accomplish reciprocal crosses of Bombina, and 5) to describe the characters of hybrid tadpoles.
