SummaryIn the genusSalamandraoccur mainly two kinds of propagation. The european spotted salamander (Salamandra salamandra) is ovoviviparous and lays a great number of larvas into the water, whereas the alpine salamander (Salamandra atra) gives birth to completely transformed gilless young ones.There are, however, several races of spotted salamander which are also viviparous. The development of such a variety,Salamandra salamandra bernardezi, is described and compared with the generation of the alpine salamander.The emancipation of the development of the larvas from their life in the water has certainly happened in several cases independent of each other under various oecological circumstances.Besides a race of spotted salamander was said to exist in a mountain lake in central Spain at about 6000 ft. This assertion proved to be wrong. The development of the embryo and the larva takes place in exactly the same way as with our native species. The results of the experiments of Mr. Kammererare dicussed on the basis of the facts at our disposal.
