Almost escaping notice because of their unusual position and their dull brown hue were the stomach fangs, in neat rows which could be extended and retracted like those of a snake. He noticed that Louise had shuddered again, and said, in the manner of a man making conversation, "Interesting, aren't they? They're rock breathers, you know.
