Abstract
The lingual papillae occurring in a female of Mandrillus maimon Linnaeus aged 7 years and weighing 10kg. and in a male of Macacus nemestrinus aged 3 years and weighing 3.4kg. have been studied respectively and the following 4 kinds of papillae commonly occurring in other vertebrates have been confirmed. Summary of the observation was as follows. 1) P. filiformes occurred as needles covering the entire dorsal surface of the tongue. The surface epithelium was considerably cornified. The papillae in the Macacus nemestrinus were particularly slender and tall in shape. 2) P. fungiformes in the Mandrillus were mainly distributed at the tip and along the lateral margins of the tongue, while those in the Macacus were located scatteringly and almost uniformly all over the dorsal surface of the tongue. There was no taste buds found with both animals. 3) P. foliatae present in the tongue of the Mandrillus numbered 12 to 17 and those in the tongue of the Macacus 7 to 9. The taste buds counted about 10 with both animals, all located in the epithelium lining the side wall of the papillae. Numerous serous glands were present in the submucosa with both animals. 4) P. vallatae occurring in the Mandrillus counted 3 and those in Macacus 6 to 8. Those occurring in the Mandrillus were roundish and of intermediate shape between that of human tongue and that of Kangaroo tongue (Kyushu Shikagaku Zassi, vol. 13, No.2). They were somewhat depressed from the surface of the tongue and the circumscribing margin extended dorsally from the papillae. In the Macacus, however, the groove of the papillae was more shallow and the papillae projected markedly above the surface of the tongue. The taste buds numbering approximately 10 were located on the inside epithelium of the papillae.
