The index as a rule is higher in the females. 



The range of the means is moderate, with Texas lowest, which 

 strengthens other indications of its anthropological separateness from 

 the rest of the Gulf States. The old native Arkansans had the highest 

 orbits, considerably higher than the otherwise related Louisianians. 

 The means of the Gulf region, however, fall well within those of the 

 North American tribes.^ 



The index in the deformed skulls is perceptibly higher than that in 

 the undeformed in all the male groups, but in the females the show- 

 ings, in two of the better represented series at least, appear to tend 

 in the opposite direction. The deformation in the males exceeds in 

 general that in the females, which may be responsible for the condi- 

 tion; but the evidence is inconclusive.
