The BULLETIN OF THE FLORIDA MUSEUM OF NATURAL HISTORY publishes research conducted by our faculty, staff, students, and research associates. We also encourage appropriate, fully funded manuscripts from external researchers. Manuscripts concerning natural history or systematic problems involving the southeastern United States or the Neotropics are especially welcome, although we will also consider research from other parts of the world. Priority is given to specimen-based research. We consider thirty-five double-spaced pages (excluding figures and tables) as the minimum length for manuscripts, although there can be exceptions as determined by the Editor and Bulletin Committee. INSTRUCTIONS FOR AUTHORS The INSTRUCTIONS FOR AUTHORS can be found on the Florida Museum web site. See http:/www.flmnh.edu/ bulletin/. We suggest authors also consult recent numbers (2005 and forward) of the BULLETIN if there are specific questions about format and style. All taxonomic papers must adhere to the rules published in the appropriate interna- tional code of systematic nomenclature. RECENT PUBLICATIONS OF THE BULLETIN Wright, J.J. & L.M. Page. 2006.
