GEOLOGICAL RANGE (Figure 38): Pleistocene. Reflexa ranges 
through a number of Pleistocene deposits within its present distri- 
bution, but has not been found fossil as far north, east or south as 
it now ranges. Kennedy’s record? from the Brazos River valley, Rob- 
ertson County, Texas, needs confirmation, as reflexa has not been 
authentically reported south of Illinois.
