The moustache and beard were entirely absent in 38.8% of 

 the cases, sparse in 18. 8%, present to a small extent in 42.4%). 

 The hair was straight in all but three cases, black in all instances 

 but two, in which the beard was brown, and two mixed black and 

 •brown. F"ive cases showed a few gray hairs. 



The observations of Hrdlicka (7) show that in the North 

 American Indian graying of the hair does not progress so rapidly 

 as in the whites, and this is also true of the Quichua. Accord- 

 ing to the results of the same author, baldness in the Indians of 

 the Southwest is rare, occurring to about the same extent as in 

 'the Quichua, 4.6% in males below 65 and .3% in females. 



In only one instance, a female (No. 99), was the panniculus 

 adiposus greatly developed. 



The breasts were conical in the females without children. 



Palpebral Fissures. 



In the male the palpebral fissures were horizontal in 55.3% 

 of the cases, slightly lower at the inner canthus in 44.7%. In the 

 female they were horizontal in 57.1%, the inner canthus depressed 

 in 41.2% and the inner canthus higher in 1.5%. The former 

 expedition found a lower inner canthus in only 26.5%. 



The Mongolian fold (epicanthus) was present in four cases, 

 two male and two female, or 2.6%, in contrast with 15% of the 

 males reported by the Expedition of 1912. One is inclined to 

 question the accuracy of the observations of the 191 5 Expedition 

 on this point. 



Eyes, Conjunctiva. 

 The eyes were grouped according to color into four classes : 

 dark brown, medium brown, light brown and black. No attempt 

 was made to distinguish between the areola and periphery of the 

 iris as in the former expedition. Of the men 88.2% were found 

 to have dark brown eyes, 1.2% light brown. 9.4^^ medium brown 

 and 1.2% black. In the female 92.6% were dark brown, 1.5% 

 were light brown and 5.9% were medium brown, indicating that 

 the eye of the female inclines to be darker than in the male. It 

 is impossible to compare these results with those of the previous 

 expedition inasmuch as the iris color was classified according to 

 the Bertillon system.
