Some of the names may not be current. I get tired of trying to keep up with all the changes in taxonomy.
This list will not be complete for a while. For many of the species I did years ago, I have no records. They will be added as I recall them. And, I have snakes gravid now that aren't on the list, and plan to add a lot more before I'm done.
