affinis and sayi can be the two closest subspecies of Pituophis. They integrade freely in areas they overlap to the point that some affinis and sayi can be very close look alikes. The catenifers, deserticolas, affinis, annectans, and sayi have been integrading in areas their ranges come in contact with the other subspecie populations quite a bit and as long as they have overlapped. The gene flow in some areas makes them hard to distinguish from each other to the point that specific locale data is the only or best way to identify it. Several ssp of catenifer can look like another ssp of catenifer and my opinion leans toward if you have verified specific locale data on the snake that it should be identified as the ssp of that locality even if it may looks like another ssp unless there's some specific reason to think otherwise. Nice looking bullsnake Greg.
:i have a Bull snake. at least that's what it was advertised as when i bought it. i just want to be sure if it is a Bull. i think i might have offended someone earlier when i said i liked the color of their Bulls when they were actually Sonoran Gophers. sorry. this is the only one i've ever had. years and years ago i thought Bulls and Gophers were the same thing. i guess i need to get re-educated. what is/are the main distinguishing difference(s) between a Bull and a Sonoran Gopher? don't both have similar coloration and a line that goes from the eye to the angle of the jaw? this is a pic of my snake.
