Abstract

We report observations of the diet of two species of terrestrial snakes: Pliocercus euryzonus was observed feeding on an egg mass, probably from of Agalychnis callidryas, while Urotheca guentheri was observed feeding on the snake Ninia maculata. These dietary items had not been reported for these snakes, so they represent an important contribution to the natural history of these two species.
