[Relations between the osseous palate and its dental laminae inSalamandra salamandra (L.) during metamorphosis].

The relations between the osseous palate and its dental laminae in larvalSalamandra salamandra (L.) during metamorphosis were examined by various amputation procedures. Removal of the mucosa and the subepithelial tissue in the region where the differentiation of the osseous bar of the vomer ("Vomerspange") takes place, does not prevent outgrowth of the bar. When this tissue material is transplanted into the subepithelial connective tissue of the body, structures similar to the bar are not formed. Amputation of the vomer and adhering connective tissue prevents the development of the bar, whereas removal of the palatinal part of the pterygopalatinum has no influence on its development. The vomerine bar does not therefore represent a "Vomeropalatinalspange" in the sense of Wintrebert. The caudal elongation of the dental lamina of the vomer is correlated with the outgrowth of the vomerine bar.
