[Observations on the teeth and the dental laminae of the upper jaw and the palate in Siphonops annulatus (Mikan) (Amphibia: Gymnophiona) (author's transl)].

Siphonops annulatus possesses a single line ("Zahnzeile") of teeth in the upper jaw as well as in the palate paralleling the curvature of the jaws. An undivided continuous dental lamina provides the 2 nasopremaxillas and both maxillaries of the maxillopalatines with teeth, whereas each vomer and each (maxillo)-palatine is toothed by a separate dental lamina. The teeth are monocuspid, pedicellate and ancylosed to the bones in an extremely pleural condition. The results are compared to the conditions observed in the palate and upper jaw of urodeles.
