These measuremeixts of extremes show there is a great amount 



of variation at single localities, in both sexes, but particularly 



in the male sex. The optimum size development of the species 



is found in the low coastal region of the Carolinas, and in the 

 north Floridian and Gulf Coast regions between Jacksonville and 



southern Mississippi, although the material continues well above 

 average size into northeastern Texas and eastern and south-central
