You need to dig further or talk with Georgia DNR. That list is pretty generic, there is actually a more detailed list somewhere on their site. I lived in Georgia for about 7 years and have been gone for approximately 6, so maybe the laws have changed. If not, then the law is actually written on a specific level. In other words, ANY Pituophis melanolucus, any Lampropeltis getula, Lampropeltis triangulum, Elaphe obsoleta, Elaphe guttata and the list goes on, would be banned UNLESS it is it's own species like Pituophis Ruthveni or similar cases like Kisatchies. So, cal kings, speckled kings, black pines, florida kings, nearly all milk snakes, corn snakes, emoryi, texas rats and so on would all be banned.
Question is, does GA enforce the laws on it's book? 7 years ago, I do know they confiscated some cal kings from a pet store in Milledgeville. Last I talked with DNR, they said it was on a specific level BUT if you could demonstrate to the officer that the snake was not a native species, they would not push the issue. So you would have to be dependent on convincing an untrained eye that your mexican milk was not in fact a scarlet king or your emoryi was not an anery corn. I was just not comfortable knowing that if they didn't believe me, then I could loose most if not all my animals. Or worse, what if you make someone mad and they "turn you in"?
Anyway, just thought I would let you know how it used to be and unfortunately, I think it still is.
