hrdliCka] skeletal REMAINS OF EARLY MAN 285 



This feature, which has been made much of, is in this case not a 

 theroid or Neanderthaloid character, due to a strong preponderance 

 of the dental portion of the bone over the basal part, but an infantile 

 form, a lack of normal development restricted to that spot. It is 

 on par with other localized infantile characteristics encountered 

 now and then in the skull or other bones, particularly in those of 

 females, though perhaps less frequentl}" than some other such fea- 

 tures. It occurs, however, now and then in the Indians and even in 

 whites (see fig. 49). 



The lower border of the chin is angular, approximating square. 

 Ventrally the bones show a fairly strong submalar (or supra-mylo- 

 hyoid) reenforcement.

 white or Indian. (U. S. Nat. Mus. No. 22/323.) 



The teeth are feminine in size and moderately worn. The right 

 lower third molar has never appeared; left (?) There is no unusual 

 feature in the relative size of the molars. The canines are incon- 

 spicuous, no diastemse.
