In December, 1980, somatological measurements were taken of the head and face, and plaster casts were prepared on the upper and lower dental arches of 65 children of Yami tribe (31 males and 34 females), aged 13 years, who occupid the small island Botel Tobagos south-east of Taiwan. Measured values of the head and face, and of the dental arch were assessed by each item, and the correlations between both values were examined. The conculusions obtained were as follows. 1. Somatological measurements 1) Males were significantly larger than females in the bigonial breadth, but not significantly in the head length, head breadth, bizygomatic breadth and morphological face height. 2) In the cranial type, males were bracycephalic and females hyperbrachycephalic. In the facial type, males were euryprosopic and females hypereuryprosopic. 2. Measurements of the dental arch 1) In the upper dental arch length, lower dental arch length, upper dental arch breadth and lower dental arch breadth, males were significantly larger than females, but not significantly in the palatal vault height. 2) In terms of indices of the dental arch, sex difference was not significant. 3. Correlations 1) Between length and length : there were no significant correlations between the head length and each of the upper and lower dental arch lengths. 2) Between length and breadth : there were no significant correlations between head length and each of the upper and lower dental arch breadths. 3) Between length and height : there was no significant correlation between the head length and palatal vault height. 4) Between breadth and breadth : there were significant positive correlations between each of the head breadth, bizygomatic breadth and biogonial breadth and each of the upper and lower dental arch breadths in all sample group divisions of males only, females only, and the total of both sexes. 5) Between breadth and length : there were no significant correlations between each of the head breadth, bizygomatic breadth and bigonial breadth and each of the upper and lower dental arch breadths. 6) Between breadth and height : there were significant positive correlations between the head breadth and palatel vault height in males, and between each of the head breadth and bizygomatic breadth and the palatal vault height, in the total of both sexes. 7) Between height and height : there wes no significtant correlation between the morphological face height and palatal vault height. 8) Between height and length : there were no significant correlations between the morphological face height and each of the upper and lower dental arch lengths. 9) Between height and breadth : there were significant positive correlations between the morphological face height and each of the upper and lower dental arch breadths in two sample group division of females only and the total of both sexes.
