Nice lists,
I'd like to list mine too. (garters and ribbons only)

I havent tried to sex them since I am not breeding them, even though I could give a good guess on nearly all of them. I do the know the sex of a few because they had babies in the past, either before or after I aquired them, or because they passed jelly beans.

Shannon, I would have you tied for species/subspecies if it werent for your "freaks"

0.0.1 California Red Sided - T. s. infernalis
0.0.1 Valley garter - T. s. fitchi
0.0.1 Coast Garter - T.e. terrestris
0.0.1 Mountain Garter - T. e. elegans
0.1.1 Northwestern Garter - T. ordinoides
0.0.1 Checkered Garter - T. marcianus
0.1.0 Sierra Garter - T. couchii
0.1.0 Mount Diablo Aquatic Garter - T. a. zaxanthus

0.2.6 Gulf Coast Ribbon - Thamnophis proximus orarius

I still want a Santa Cruz - T.a. atratus. Then that about does it for me(at least with native garters) due to regulations of what I can have and how many per species. Once I find that Reptile-loving Christian Reformed wife with a fishing license we can add a T. e. vagrans and T. a. hydrophilus to the listto complete the list of 11 varieties(out of 14 total) of native garters that arent protected. The s.f, giant, and 2- striped are protected.
