Abstract

Lingual papillae were histologically studied on a male Ammotragus lervia aged 4 and a male sheep aged 12. The results were summarized as follows. 1) In both animals Papillae vallatae were located on the dorsal surface of the posterior part of the tongue. They counted in the Ammotragus lervia 12 to 15 arranged in a row and in the sheep 20 to 25 arranged in two to four rows along each side of the tongue. The taste buds counted approximately 5 to 10 in the Ammotragus lervia and 4 to 5 in the sheep along each side of the tongue localized on the epithelium facing the circumscribing groove of the papillae. 2) Papillae fungiformes were distributed over the entire dorsal surface of the tongue, and especially densely on the dorsal surface and the lateral margin of the anterior part of the tongue. In both animals they counted approximately 200, and lacked the taste buds. 3) Papillae filiformes occurred as needles covering the entire dorsal surface and the lateral margin of the anterior part of the tongue.
