• Observations in vivo on the contours, the types of the groove on the dorsum of tongue and the type of plica fimbriata have been conducted on the primary school children 6 to 11 years old, residing in 4 regions of Amakusa island, the cities of Kumamoto, Fukuoka and Kokura. The subjects examined for the observation of tongue contours numbered 1066 in total, and those for the observation of the groove types 1909 and fimbriate folds 1832 in total. The results obtained were summarized as follows. The types of tongue's contour were classiffed into 5 as illustrated in Fig.I. (by Nishijima et al. 1957) The rate of occurrence of each type was as follows : u-type 42%, narrower u-type 10.8%, broader u-type 29.4%. round type 6.2% and V-type 11.6%. Although the percentages of occurrence of these types as revealed in the present investigation disclosed certain minor deviations present from those reported by Biegert (1954) on the German and by Nishjzima et al. on the Japanese and the Ainu, the order in the magnitude of frequency between types generally coincided with each other. The types of groove on the dorsum of tongue were classified into 7(Fig.3). The average rates of occurrence of these types were 30.4% in the longitudinal type, 24.5% in the longitudinal and transversal type, 23.3% in the lacking type, 14.7% in the transversal type, below 10% in the confused type. Very few instance were found in regard to lattice type and circumscribing type of groove. Comparison of the data for distribution and frequencies of these groove types indicated that the data for the inhabitant of Amakusa was grossly identical to those for the pure Ainu (Nishijima), while the data for the inhahitants of Kumamoto, Fukuoka and Kokura did not show any similarity to those of the German by Biegert and those of the Japanese and Ainu by Nishijima in general, except a few instances of groove type where these peoples were in common. The fimbriated folds The fimbriated folds of the tongue were classified into 3 types, the 1st, 2nd and 3rd. (Fig.4a, b) The order in the magnitude of frequency of these types was as follows ; the 2nd type 48.6%, the 1st type 28.4% and 3rd type 23.0% in the inhabitants of Amakusa island. For the inhabitants of Kumamoto, Fukuoka and Kokura cities the order is the 2nd, 3rd and 1st types. The figures for these cities were as follows ; the 2nd type 54%, the 3rd type 40.1%, the 1st type 5.9% in Fukuoka, the 2nd 69.8%, the 3rd 24.2%, the 1st 6% in Kumamato, and the 2nd 58.6%, the 3rd 36.7%, the 1st 4.7% in Kokura.
