But like Chantel said, most of the time when people refer to the common garter snake, they are referring to easterns....the subspecies Thamnophis sirtalis sirtalis. And like Chantel said, there are many species of garters and ribbons.
I don't think you have that right. I think when an animal has been classified into a subspecies the common name for the subspecies applies, and not the common name of the parent species. In the case of T. sirtalis, you wouldn't call a tetrataenia, infernalis, or concinnus a "Common Garter" - they have been classified as subspecies with their own common name, therefore you wouldn't use the common name for the species they belong to when you have a more accurate subspecies name.
