A good question from Art Weil: The tornado is coming and I can grab only three shells? I'd grab my field notes and leave the shells behind. After all, I can collect more shells if I know where to look. Which three volumes to choose is another matter entirely! Andrew K. Rindsberg Geological Survey of Alabama P.S. Gary Rosenberg is correct, the technical term in taxonomy is "first revisor" (or "reviser"), not "first reviewer". I thought something didn't sound right but couldn't put my finger on it. Thanks, Gary.
