The aim of this study is to clarify the traits of the Dafurs's head, face and dental arch. In August and September of 1996, somatological measurements were taken of the head and face and plaster models of 190 Dafurs young adults (92 males and 98 females), inhabitants of Halaer City of China. Measured values of head and face, and of the dental arch were assessed by each item. Each value of the Dafurs was compared with that of other tribes living in north-east of China and Japanese. Furthermore, the correlations between the measurements of head and face, and those of dental arches and palate height were examined. The results obtained were as follows : 1. Measurements of the head and face. 1) Head length : The mean value for the male is 177.7 mm of the Short Type, and for the female 173.2 mm of the Middle Type. 2) Head breadth : The mean value for the male is 153.2 mm of the Middle Type, and for the female 150.0 mm of the Wide Type. 3) Bizygomatic breadth : The mean value for the male is 126.5 mm of the Very narrow Type, and for the female 125.3 mm of the Narrow Type. 4) Morphological facial height : The mean value for the male is 121.5 mm of the Middle Type, and for the female 118.9 mm of the High Type. 5) Cephalic index : The mean value for the male is 86.33, and for the fepale is 86.71, both of the Hyperbrachycephalic Type. 6) Morphological facial index : The mean value for the male is 96.11, and for the female is 95.04, both of the Hyperleptoprosopic Type. 2. Measurements of the dental arch. The shape of dental arch in Dafurs tribe is the similar to the Man tribe, the Mongol tribe and Japanese. 3. Correlation : In male significant positive correlation was shown between palate height and head height, palate height and physiognomical facial height, palate height and morphological facial height. In female significant positive correlation was only shown between the upper dental arch breadth and physiognomical facial height.
