We thank L.H. Taylor, C. Bell, and L.L. Jacobs for the opportunity to contribute to this volume honoring our friend Rep. We are in debt to all our Siwalik friends for building the collection, in particular to L.L. Jacobs, W. Downs, J. Barry (who recognized the lagomorph post crania), and M. Morgan (who found Bunny Hill). Roy Beavers, at Southern Methodist University, Dallas, Texas, took the SEM photomicrographs. We appreciate the comments of two anonymous reviewers on a draft of the manuscript. Grants from the National Science Foundation, National Geographic, Smithsonian Foreign Travel Program, and Peabody Museum, Harvard University, funded this work.
