PROCEEDINGS OF THE UNITED STATES NATIONAL MUSEUM issued iMr^vva-^u^l ^y the SMITHSONIAN INSTITUTION U. S. NATIONAL MUSEUM Vol. 101 Washington: 1951 No. 3284 NOTES ON A HERPETOLOGICAL COLLECTION FROM OAXACA AND OTHER LOCALITIES IN MEXICO By Frederick A. Shannon During the summer of 1946, Walter S. Miller, of the Summer Institute of Linguistics, Mexico City, made a herpetological collection in the vicinity of San Lucas Camotlan, Oaxaca, where he was en-gaged in making a philological study of the Mixes Indians. The collection would be to the credit of a professional herpetologist, for not only is it well labeled as to time, date, and place, but it contains careful notes on habits, color in life, habitat, and other pertinent data. Notes on this material constitute the bulk of this paper, which is a Contribution from the University of Illinois Museum of Natural History. In addition, other miscellaneous specimens that have come to my attention during this study and material that represents helpful contributions to the study of Mexican herpetology have been included. Most of the specimens are in the collection of the United States Na-tional Museum. Quotations without label are Mr. Miller's. In the main they are unaltered, but I have made occasional slight changes that better express the meaning of Mr. Miller's original field notes. INIy sincere thanks are due Dr. Hobart M. Smith and W. Leslie Burger, both of the University of Illinois — to Dr. Smith for many helpful suggestions made during the course of this study, and to Mr. Burger for identifying the Bothrops^ a discussion of which is published elsewhere. My thanks are also due my wife, Ellen Jordan Shannon, who illustrated the paper. I also thank Dr. Doris M. Cochran, of the United States National Museum staff, through whom arrangements 913683—51 465
