Introduction There is not much evidence in the literature, at least in the former USSR, of cases of hermaphroditism and anomalies in the inner organs of reptiles and amphibi- ans. Terentyev (1950) reported the anomalies of the gonads in various frog species, which were recorded by other researchers. Yakovleva (1964) observed a combination of male and female sexual organs in Vipera ursini from the vicinity of the city of Frunze (currently Bishkek), Kyrgyzstan. Brushko (1968) and Radzhabov (1975( described cases of hermaphrodit- ism in Elaphc dione and anomalies of the gonads in Coluber ravergieri and Elaphe Dione. During the whole period of collection of the mate- rial on the ecology of tailless amphibians in Uzbeki- stan (1971-1995), the authors recorded the individuals of Bufo viridis showing anomalies in their gonads. rVa> ml BS (% CO \*-',iv-«\y L *;.â .* *:,'y <*S?
