title: [Organization of the osseous nasal septum and its homologues. III. The sphenoid bone and the vomero-transversal system in Urodela].
abstract: In connection with the comparative anatomical examinations of the nasal septum in man, the urodela skulls were examined . The aim of these investigations of the osseous median palatal part and sphenoethmoidal bone were evaluated. 25 skulls of adults frogs were examined. It was stated that parasphenoid in these Amphibians consisted of two parts: agger vomeris and lamina transversalis. These elements were the homologue to the parasphenoideum seu vomero-transversale system in fishes. The premaxilla in frogs belonged (substituted) to the maxillary++ arch. The sphenoethmoidal bone in frogs were the same as the alar bone in birds (part I) and fishes (part II). In all frogs the author did not found any "mesoethmoid ". These precedential facts, observed in birds (I), fishes (II) and amphibians (III) led to further study in mammals and man.
