Some of the Pleistocene mammals from San Josecito Cave, nearAramberri, Nuevo León, México, collected by field parties of theCalifornia Institute of Technology under the direction of the lateProfessor Chester Stock, have been reported previously (see Furlong,1943; Cushing, 1945; Stock, 1950; Hooper, 1952; Findley,1953; Stock, 1953; Handley, 1955; Jackway, 1958). In 1950, ProfessorStock loaned a portion of the San Josecito material to theUniversity of Kansas for identification. Included therein were 89crania and rami of bats, representing three families (Phyllostomidae,Desmodontidae and Vespertilionidae) and five genera, each representedby a single species. One of the species is here described asnew. Three of the kinds are known only from the Pleistocene andtwo are Recent species.
The only previous mention of fossil bats from México known tome concerns material from San Josecito Cave. Cushing (1945:182)mentioned a "vampire bat" from the cave (see also Maldonado-Koerdell,1948:17), and Handley (1955:48) based his description ofCorynorhinus tetralophodon on a specimen from San Josecito.
Brief descriptions of the cave have been published by Miller(1943) and Stock (1943). The precise age of the deposits is unknown;stratification data did not accompany the material senton loan to the University of Kansas. However, most of the micro-faunais thought to have come from the higher levels in the caveand is probably late Pleistocene.
The San Josecito Cave collections are currently the property ofthe Los Angeles County Museum.
I am grateful to Dr. E. Raymond Hall for permission to study thebats from San Josecito Cave, to Dr. Robert W. Wilson for criticismof the manuscript, and to Mr. Philip Hershkovitz for permission touse comparative material at the Chicago Natural History Museum.Lucy Rempel made the drawings from photographs by John M.Legler.

Remarks.—The long-nosed bats from San Josecito Cave do notdiffer appreciably from Leptonycteris nivalis longala Stains, thelargest Recent subspecies of the species, and the subspecies thatoccurs in the same geogra
