Metlapilcoatlus nummifer

It is thick, cylindrical; when seen from afar it is not apparent where its mouth is. At both ends it is like a mano; at both ends it is pointed; it is just like something smoky, dark. As it travels, it slithers, and sometimes it only rolls like a mano. Yet it is not poisonous, not harmful. It lives especially there in the Totonac region.
