Taxonomic Notes on Mexican Bats of the Genus Rhogeessa by Eugene Raymond Hall

Five skins with skulls of _Rhogeessa_, collected by J. R. Alcorn in the states of Sonora and Nayarit of western Mexico, were recently received at the Museum of Natural History of the University of Kansas. Two other specimens of the same genus, collected by Walter W. Dalquest in the state of Veracruz of eastern Mexico, also are in the Museum of Natural History. With the aim of applying names to these bats they were compared with materials in the United States National Museum (including the Biological Surveys collection) where there are approximately the same number of Mexican specimens of _Rhogeessa_ as are in the Museum of Natural History.

The three kinds of _Rhogeessa_ named from Mexico are as follows: _R. parvula_ from the Tres Marias Islands off the west coast of Nayarit; _R. tumida_ from Mirador, Veracruz, on the eastern slope of the Republic; and _R. gracilis_ from Piaxtla, Puebla, on the southern end of the Mexican Plateau.
