the study. O. F. Anderson, C. Duke, D. Tucker, and R. L. Herrington 
aided in field work. Earlier drafts of this manuscript were substantially 
improved by comments from R. Mount, R. Wallace, J. Beneski, B. 
Miller, and G. Zug. Special appreciation is extended to my wife Vicki 
for preparing the histological material used in this study.
