Bothrops atrox

It is of average size, about like the tecutlacoçauhqui. It is smoky. And it is called palancacoatl because it stinks, and its body looks as if it were full of sores, as if it lay mouldering. On it lie flies swarming. And wherever it travels the road, there it goes stinking; with it the flies go swarming, they go along buzzing. And it is indeed a palancacoatl: whomever it bites no more escapes; it has no cure, so that he dies, he is consumed by the suppuration.
