Summary. 



Eighteen males and fifteen females were measured and photo- 

 graphed. 



The skin is medium or red brown (paint?) in the males and 

 mostly medium brown in the females. In both sexes the face 

 is streaked with red paint. 



The hair is a rusty dull black, in most cases straight, but in a 

 few males slightly wavy. 



Alopecia is infrequent, gray hair is rarely observed, and the 

 moustache and beard are scanty or absent. 



The eyes are dark brown and the conjunctivae yellowish in 

 both sexes. The palpebral fissures are slightly inclined upward 

 at the outer end. The forehead is of medium height, the supra- 

 orbital region of medium development, the jaws and chin are 

 medium in projection and the lips medium in thickness and 

 protrusion. The face is broad and the malars are prominent in 

 both sexes. 



The ear is medium in size and mesotic or microtic in most 

 individuals of both sexes. 



The dorsum of the nose is generally convex in the male but 

 less frequently in the female, the nasal root is markedly depressed 

 in many of both sexes, and the base inclined up in the majority 

 of cases. The nose is chiefly mesorrhine or chamaerrhine. 



The Machiganga are of "low stature" (1559 5) and some- 

 what shorter than the Quichua, the height of the female being 

 120 millimeters less than that of the male. The span and height 

 are equal, in the male ; the span slightly less in the female. Their 

 bodies are short and lower extremities long. The hands and feet 

 are small and somewhat slender, especially in the female. The 

 handgrip is weak and less than in the Quichua. 



The stature-leg circumference index is smaller than in the 

 Quichua and is larger in the female than the male. 



The thoracic diameters are less than in the Quichua and the 

 index is considerably larger (79.4^ and 79.3? ), showing that the 

 Machiganga are relatively narrow chested. 



The head diameters, with the exception of the height and the 

 modulus, are small in comparison with those of the Quichua 

 and of most other races. All the diameters are smaller in the 

 female, except the height, which is the same in both sexes.
