St. Mary’s River, I took G. floridanus typicus , while Sterling, 
Georgia, is the nearest point north of St. Mary’s, Georgia, at which 
Mr. Brown got G. tuza. What happens to the westward I am 
unable to say. 
The very dark color of G. colonus will at once distinguish it from 
either tuza or floridanus, as do also its constant cranial characters.
