Questionable and/or Erroneous Records: Gentry (1956) stated that Crotalus horridus atricaudatus “has been taken on or near the shores of Kentucky Lake (Tennessee River) especially in Stewart, Benton, Decatur, Humphreys, and Henderson counties.” All of the counties listed, except Henderson, border Kentucky Lake; however, Henderson County is neither on nor near the shores of the lake. Therefore, we consider the record from Henderson County to be questionable.
