Three-Banded Coit
One of the more bad-tempered and lethally venomous snakes of the Genuan delta. Granny Weatherwax did not know this when she picked one up by the tail, although it had reptilian sense enough to keep its jaws firmly closed when it saw the expression on her face and put up with the indignity. It might even have heard of that local delicacy, snake's head soup.
