APPRAISAL OF PHYSICAL DATA 



Metrically, the tribes of the Upper Xingu Basin 

 appear to be much alike (table 1). This is the 

 more surprising since from the small number of 

 subjects in all but Ranke 's Nahuqua (Nahukwa) 

 series one would expect unrepresentative samples 

 and divergent mean figures. It is especially note- 

 worthy that, after due allowances for technical 

 differences are made, Ehrenreich's and Ranke's 

 means for the Aueti, Trumai, and Nahuqua are 

 very similar indeed. Taken as a group, the Upper 

 Xingu series have a mean range in stature of 158- 

 164 cm., with the Camayura" the tallest. The 

 mean cephalic indices cluster closely around 80. 

 All Ehrenreich's series are rather low-headed, 

 with means from 82-87 in the breadth-height 

 index. The highest mean (86.7), possibly a real 

 indication of difference (see below), comes from 

 7 Trumai males. Ehrenreich's mean facial indices 

 are medium, ranging from 84-87, while Ranke's 

 three series have means of 88 and over, and are 

 probably more correct (p. 131). The same is true 

 of the mean nasal indices, which, for Ehrenreich's 

 series range from 75-78, within the medium cate- 

 gory; for Ranke's, from 69-75. The similarities 

 between the Upper Xingu series, on this crude 

 metric basis, suggest that they represent a single 

 racial unit, or part of one. But since Ehrenreich
