The epithelial cell layer was removed from the underlying connective tissue papillae by the method of long term hydrochloric acid treatment and the connective tissue surface was observed by scanning electron microscopy. Tongues of insectivora (Suncus murinus), rodentia (mouse, rat, guinea pig), carnivores (dog, cat) and primates (man) were studied. Each animal species had proper architecture of connective tissue papillae as to four types of lingual papillae. There was a tendency for the stereo structure of connective tissue papillae of these lingual papillae to become more complicated from insectivora to primates.
