The nasal index, barring Texas, is throughout of medium propor- 

 tions (mesorhinic) ; in Texas alone it rises toward platyrhiny. This 

 is one more difference which separates Texas crania from those of the 

 rest of the Gulf States. 



In the female skulls the index tends mostly to be slightly higher 

 than in the males, owing to predominantly lower relative height of 

 the female nose. 



The deformed skulls show no regular significant difference in nasal 

 index. 



The mesorhinic type of nose is widely represented in North American 

 tribes.^ 



INDEX OF THE UPPER ALVEOLAR ARCH 



The upper alveolar arch presents evidently regional differences of 

 some significance. It is relatively broader in Florida and Georgia, 

 and also Louisiana, than it is in the other States. The group range 

 falls well within that of other North American tribes.^ 



Sex differences in the index are irregular and doubtless mostly 

 unreliable owing to inadequate numbers of specimens. 



The arch in the deformed in the majority of cases appears relatively 

 slightly narrower, but there are exceptions, and the differences in the 

 numbers of specimens in some of the cases make matters uncertain.
