Abstract
From the histochemical analysis of the tongue of Cynops pyrrhogaster pyrrhogaster, it has been possible to establish that the lingual glands and the goblet cells show a variety of cellular types which display typical histochemical reaction to mucopolysaccharides and proteins. In the terminal portions of the lingual glands every cell produces secretory granules consisting of mucopolysaccharides and proteins, but in the cervical portions the secretory cells contain hardly any protein substance. The goblet cells scattered on the ventral epithelium contain both neutral and acid mucopolysaccharides.
