Abstract：
:The system of lateral-line organs in urodeles was examined by the use of various light- and electron-microscopical techniques. The results show that, in addition to the well-known mechanoreceptive neuromast organs, a second type of receptor can be identified. This second type of organ was presumably seen by earlier workers, but they seemingly failed to point out the distinction between the two organs. The presently described organs are anatomically similar to the ampullary organs of various anamniotic species such as Brachiopterygii, sturgeons, lungfish, and silurids. In all these species the ampullary organs display only one afferent fiber but no efferent innervation and are situated around an ampullary enlargement in or below the epidermis as in urodeles. All ampullary receptors including those of urodeles are very sensitive to weak electrical fields. Similar to the situation in teleosts, the ampullae of urodeles show numerous microvilli but no kinocilia. All other nonteleostean ampullary receptors appear to possess only kinocilia as apical specializations but no microvilli. Current evidence suggests that the electroreceptive ampullary organs are as phylogenetically old as all other vertebrate sensory systems; they are now known to be relatively common among anamniotic vertebrates. Since all ampullary receptors share many common characteristics, it is assumed that they were derived from one phylogenetic precursor but have evolved certain peculiarities in each species not shared by other ampullary receptors.
