I'm a novice hand at this, so I was hoping for a little guidance. If I posted photos of a mixed group of local garters that was dropped off on me, could I borrow your collected experience and brains on which is what and what is which? I can sex them just fine, but figuring out if these are all variations of the same species, or different ones is giving me a headache. Most of these are T. marcianus, but there's enough color variation in a few that I'm not sure about them.

Does anyone mind? If not, pictures will be incoming.
