They live under rocks on cedar glades and are said to be "so secretive that few people encounter it" although we have at least one come down from our overgrown cedar glade almost yearly. They are found in southern Missouri and on through the south central US. Another name for them is "ground rattler" - in opposition to what, an aerial rattler? That is one I don't want to see.
Herps of Arkansas has a lot more information on them.
