Thanks for posting some of the Mexican garters I have seen mentioned but i have no listing of.

[brain]

I got this list from Stefan a few months back and thought I would post it. Thanks Stefan.
So many garter snakes. So little time

I didn't realize there were so many species.

[guidofatherof5]

Such a wonderful species.
They are all quite Thamulous

[RedSidedSPR]

Oh, that was just awful

[snakehill]

Difference between a Great Plains garter and a Plains garter? Steve? (size? location?)

[guidofatherof5]

I believe the only difference is the word "Great".

It's just another acceptable name for the same snake.
To be honest I've never seen them called "Great Plains Garter Snake" anywhere but on this list.

Checking into this I found a reference:
Plains Garter Snake

I also found a reference to "Great Plains Garter Snake" on Youtube.
Sounds like it's connected with a location also.
Hope this helps

By any other name would be as sweet"

[snakehill]

Also when I googled Great Plains garter, Eastern Plains garter came up. Is this correct? I thought there was no such thing as an Eastern Plains! I am confused!

[guidofatherof5]

I didn't find that when I search but it may be referring to "Eastern" as a part of the Plains garter snake range.

Not to be confused with the Eastern Garter Snake(Thamnophis sirtalis sirtalis).

All of this refers to Thamnohis radix.
In my opinion.

[snakehill]

It said Thamnophis Radix Radix. Found only in Marion and Wyandot counties in Ohio but also found in Northeastern Indiana. Huh?
