24O AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 



The scapular and infrascapular indices corresponded fairly well 

 with those given by Flower. 1 These indices form a marked ex 

 ception to the primitive traits usually found in Eskimo skeletons, 

 for they are at the other extreme from those of the anthropoids, 

 while the indices of Europeans occupy a position about midway 

 between. 



The right glenoid fossa of 5864 is larger than the left, the di 

 mensions being 42x28.2 and 42x27.1, respectively. 



In all the scapulae examined, the superior border forms a deep, 

 almost U-shaped notch, the characteristic being most exaggerated 

 in 5864 and least so in 5429, in which the suprascapular notch is 

 well marked. This concavity of the superior border of the scapula 

 appears to be a racial characteristic, being more .or less common 

 throughout all the Eskimo groups. It rarely occurs in whites or 

 Indians. The scapulae of a gorilla in the Wistar Institute collection 

 shows this same concavity, the resemblance being striking. On the 

 other hand, it did not occur in any of eight orang utan skeletons 

 examined. The cause of this anomaly is not evident in the culture 

 of the Eskimo, and it may well be an inherited evolutionary trait. 



Clavicle. Special mention has been made elsewhere of the 

 lengthening and strengthening of the clavicle on the right side in 

 connection with asymmetry of the first rib. The bones are other 

 wise normal, being fairly strong, with roughenings for muscular 

 attachment well, but not excessively developed.

Humerus. The humeri of 5863 were both perforated in the 

 olecranon fossa, the openings being of fair size, and the left larger 

 than the right. This seems to be a primitive, although scarcely 

 simian characteristic, being of more frequent occurrence in the 

 anthropoids than in man, and in the ancient than the modern 

 races. Even in the anthropoids it is an individual variation. Its 

 most frequent occurrence among human beings is in prehistoric
