By macerating surrounding tissues with concentrated hydrochloric acid (Yoshioka, '49), path of each canaliculus was studied in six species of urodeles (Hynobius tokyoensis, H. lichenatus, H. nigrescens, H. retardatus, Onychodactylus japonicus, and Triturus pyrrhogaster), and four new types were discovered which were named conveniently as follows: (A) Type 1-transversal: found in all of the six species investigated (Figs. 1. 2. 3). (B) Type 3-grouping-transversal: in H. tokyoensis and H. lichenatus (Figs. 2, 3). (C) Type 3-connective-transversal: in H. nigrescens, H. tokyoensis and H. retardatus (Figs. 2, 3). (D) Type 3-isolated-transversal: in H. lichenatus (Fig. 3). Phylogenetic interrelations are recognizable among these types so that the type 3-isolated-transversal is supposed to be derived from the type 3-connective-transversal, and this from the type 3-grouping-transversal. In all of the six urodele species, canaliculi of simpler and more primitive types are localized in rather anterior parts of kidneys, but toward the posterior they grow more complicated and differentiated. Details of the structure in Triturus pyrrhogaster and further considerations on phylogeny of all the urodele kidneys will be given in another paper.
