Abstract
Following a prolonged bite by a large specimen of the wandering garter snake (T. elegans vagrans), symptoms of envenomation rapidly developed. Swelling, edema, pain and localized hemorrhage occurred but without the subsequent onset of systemic manifestations. The bite recipient was examined and the evolution of poisoning monitored. Depending upon duration of bite and inclination of the snake, members of this species are capable of occasionally causing mild envenomation in humans, including localized poisoning not unlike that seen following bites by small Crotalidae (pit vipers).
