Pituophis deppei

It is of average size. It is like the poisonous serpent, the chiauitl. It has no rattles, nor is it poisonous. It is painted yellow, ruddy, dark; it resembles the tecutlacoçauhqui. It is broad-headed, big-mouthed, large-mouthed; not a bearer of young but an egg-layer, an egg-producer, a hatcher, a nest-maker. It is one which coils about one; not poisonous, just a striker; one which swallows things whole. It has no poison, no venom. It strikes, swallows, swallows whole, coils itself about one. Thus does it kill: once a coyote was seen seated on the grass by the edge of the road, its face very much swollen; it had protruded its eyes. And a traveler came upon it. It was beckoning to him with its paw; like a man was this coyote. Then the traveler went toward it and saw that a cincoatl was coiled about its neck and its legs; it protruded from its flank. Thus [the serpent] could kill it. Then the traveler took a stick; he repeatedly beat the serpent with it. Then the cincoatl uncoiled and fell to the ground, whereupon the coyote fled. Later the coyote paid its debt well, for it gave many birds to this warrior who had saved it.
