Despite this' lack of unity and the great area they inhabit, their 

 dialects are mutually intelligible and in other respects they are so 

 similar that I believe we are justified in regarding them as one group 

 linguistically, physically, and culturally. 



DESCRIPTION. 



Measurements made on fifteen men and five women gave the fol- 

 lowing results: 



Height — Men: Maximum 161.3 cm., minimum 145.1 cm., average 

 153.9 cm. 



Women: Maximum 152.3 cm., minimum 144. 1 cm., average 

 146.8 cm. 



Cephalic index — Men : Maximum 89. 1 , minimum 76.3, average 84.6. 



Women: Maximum 84.8, minimum 75.2, average 81.3. 



Length-height index — Men: maximum 78.7, minimum 64.5, average 

 74.2. 



Women: Maximum 81.8, minimum 75.0, average 77.4. 



From these figures it appears that there is considerable variation 

 between individuals, but a closer study of the charts shows that the 

 majority of those measured come closer to the averages than do the 

 members of any other group here mentioned (Plates LXIV-LXIX). 



Both sexes wear the hair long and comb it to a knot at the back of 

 the head. The women generally bang the hair over the forehead, while 

 the men allow a lock to fall in front of each ear. The hair is brown- 

 black and generally slightly wavy, although four individuals with straight 

 hair were seen. 



The forehead is high, and in about half the persons observed some- 

 what retreating; however, full, vaulted foreheads are by no means un- 

 common. The distance from the vertex to the tragus is uniformly 

 great. 



The cheek bones are quite prominent, while the whole face tapers 

 from above so as to be somewhat angular. In twenty per cent of the 

 men the root of the nose seemed to be continuous with the supra- 

 orbital ridge, which, in such cases, was strongly marked. In general 

 the root of the nose is broad, low, and depressed, and there is a tendency 

 for the ridge to be somewhat concave. The lips are thick and bowed, 

 but there is little or no prognathism. 



The skin of the body is not tattooed or mutilated in any other way, 

 but the eyebrows are often shaved to a thin line, and the teeth are filed 

 and blackened. Filing was formerly done with small stones but im- 

 ported files are now used for this purpose. The coloring is effected
