Red Belly

[bradlush]

So I'm looking at a Kijiji ad regarding Ring Neck Red Belly snakes. I live in Nova Scotia and it's illegal here to own any animal that is indigenous to the province. I've found that Red Bellies are found from Florida to Nova Scotia. So just to be safe... anyone know how to tell sub-species from one another?

Here's the ad.

Any help would be great as it would be a perfect anniversary gift for my girlfriend.

Thanks.
