Abstract

Three caves in Guadalupe Mountains National Park, Culberson County, Texas, are closely grouped spatially, and their fossil-bearing sediments are about the same late Pleistocene age. Publications concerning two of the caves, Upper Sloth Cave and Lower Sloth Cave, list and discuss their fossil faunas. Here, we add identifications of mammals from the third site, Dust Cave, and briefly comment on selected taxa. Tamias canipes or T. quadrivittatus (gray-footed or Colorado chipmunk), Tamias minimus (least chipmunk), Reithrodontomys (harvest mouse), Sigmodon ochrognathus (yellow-nosed cotton rat), Aztlanolagus agilis (Aztlán rabbit), and Sorex nanus (dwarf shrew) are added to the faunal list of the cave complex. More questionable identifications of taxa not recorded from the other caves include Ictidomys tridecemlineatus (thirteen-lined ground squirrel), Thomomys talpoides (northern pocket gopher), and Capromeryx (miniature pronghorns). Reexamination of several taxa from the Sloth caves did not confirm published records of Cryptotis parva (least shrew), but added Sorex merriami (Merriam's shrew) and confirmed the presence of Neotoma mexicana (Mexican woodrat) and Sorex cinereus (masked shrew).

Tres cuevas en el Parque Nacional Guadalupe Mountains, condado de Culberson, Texas, están cerca de si, y sus sedimentos con fósiles representan aproximadamente el mismo periodo del pleistoceno tardío. Las publicaciones con respecto a dos de las cuevas, Upper Sloth Cave y Lower Sloth Cave, enlistan y discuten su fauna fósil. Aquí, agregamos identificaciones de mamíferos de la tercera cueva, Dust Cave, y brevemente comentamos sobre algunos taxa seleccionados. Tamias canipes o T. quadrivittatus (ardilla de pata gris o ardilla de Colorado), Tamias minimus (ardilla rayada menor), Reithrodontomys (ratón de cosecha), Sigmodon ochrognathus (rata algodonera de nariz amarilla), Aztlanolagus agilis (conejo de Aztlán), y Sorex nanus (musaraña enana) son añadidas a la lista de la fauna del complejo de cuevas. Identificación menos confiable de otros taxa que no fueron registrados para las otras cuevas incluyen Ictidomys tridecemlineatus (ardilla de tierra de trece líneas), Thomomys talpoides (tuza norteña), y Capromeryx (antílope miniatura). La revisión de varios taxa de las dos cuevas de Sloth no confirmó los registros publicados de Cryptotis parva (musaraña menor), pero agregó Sorex merriami (musaraña de Merriam) y confirmó la presencia de Neotoma mexicana (rata maderera) y Sorex cinereus (musaraña enmascarada).
