Really? I thought both sub-species ate the same things (including snails). So you're telling me that only the Northerns have the specialized teeth? BTW, if anyone else wants to know, the teeth of a Northern Brown snake (I don't know about Midlands yet) are larger on one side and smaller on the other side so they can grip the round shell of a snail to force the flesh out of the shell and into the NBS's gaping jaws.
