the projection of the chin was pronounced either in the male or 

 female. 



The only sex ditTerence in the prominence of the chin is that 

 the supramediiim chin is somewhat more frequent in the male. 



In the male 12.9% show medium projection of the malars. 

 65.9% supramedium. i.2'/{ submedium. and 20% pronounced. 



In the females 11.8% are medium in projection. 66.2*^^ above 

 niedium, 22% pronounced, and none submedium. 



The malars are therefore more prominent in the Quichua than 

 in the white races, with little difference in the two sexes. 



Forehead. 



The height of the forehead is measured from the nasion to the 

 crinion in the median line. Occasionally the hair line slopes 

 downward as it approaches the median line. In such cases this 

 measurement is unsatisfactory. As alopecia is a very unusual 

 condition in the Quichua. observations on the forehead height 

 are more satisfactory than in most races. 



The average nasion-crinion height in the male is 48. the 

 extremes are 66 and 26, and the variation range 40. In the 

 female the average is 43, the greatest 57, the least 29, and the 

 variation range 28. The forehead of the female Quichua is 

 therefore less in height and the variation is not so great as in 

 the male. 



Hrdlicka found the average forehead height in the natives of 

 the Kharga Oasis to be 62. which he remarks is noticeably less 

 than in most groups of male whites and other races exclusive of 

 the Indian and most of the Negroes. 



The seriation tables indicate well the greater range of varia- 

 tion and higher average found in the male. 



The forehead of the Quichua according" to these observations 

 is very low and probably can be e.xplained as in the case of the 

 large face height determinations 1)\- the placing of the nasion too 

 high. 



The forehead height as determined by inspection shows in the 

 males 77.47^ medium. 21.4^^ submedium. and 1.2% supramedium ; 

 in the females the results are 70.6' r medium. 287^^ submedium.
