An Annotated Checklist and Key to the Snakes of Mexico, Ausgaben 187-189U.S. Government Printing Office, 1945 - 239 Seiten This bulletin supplies checklists and keys for identification of Mexican snake species. This work arose partially out of a joint, active interest resulting from a collecting trip to Mexico in 1932. Additionally, in gathering information, the authors studied specimens in the United States National Museum and other collections. The authors acknowledge that this treatise can be revised over the years as new materials are found and described. Where available, the authors have included United States National Museum catalog numbers for type specimens in the species descriptions. |
