While watching the Super Bowl I was scanning though my "Snakes of North America"-Eastern and Central Regions Field Guide when I saw a group of photos featuring Storeria. He's the list of snakes. Not sure if all these are recognized as this book was printed in 2003.
In any event I had no idea there were so many.
Little brown snakes are awesome.

Northern Red-bellied Snake (Storeria occipitomaculate occipitomaculate)
Florida Red-bellied Snake (Storeria o.obscura)
Black Hills Red-bellied Snake (Storeria o.pahasapae)
Northern Brown Snake (Storeria dekayi dekayi)
Florida Brown Snake (Storeria d.victa)
Midland Brown Snake (Storeria d.wrightorum)
Texas Brown Snake (Storeria d.texana)
Marsh Brown Snake (Storeria d.limnetes)
