N1 - Funding Information:
Study of Atopomys texensis was begun as part of Winkler's Masters Thesis at the University of Texas at Austin, supported by grants from the University of Texas Geology Foundation and the Geological Society of America. We thank the National Speleological Society for permission to make collections in Hamilton Cave. Excavations in Hamilton Cave were in part supported by a grant from the National Geographic Society to B. Van Valkenburgh, B. Kurten, and F. Grady. Many volunteers helped in the excavation ofHamilton Cave, in particular T. Kaye, B. Hoke, M. Drake, D. West, and C. and D. Keller. C. Repenning, R. Martin, R. Zakrzewski, A. Barnosky, D. Winkler, L. Jacobs, and N. Hotton provided helpful critiques ofthe manuscript. R. Martin kindly brought the Florida mandible to our attention and N. Czaplewski provided a cast of "Nebraskomys" from the Verde Formation. We especially appreciate the many discussions with C. Repenning about arvicoline rodents. D. Winkler drew Figure 3. We also thank A. Barnosky, P. Gingerich, G. Gunnell, G. Morgan, R. Purdy, and M. Winans for the loan of specimens used in this study.

N2 - New records of Atopomys salvelinus from West Virginia and Florida, and additional remains of A. texensis from Texas are reported. A partial mandible of A. salvelinus with M1-2 from Alachua County, Florida, is the first record of the genus from that state, and the most complete specimen of Atopomys known. Although M3s of A. texensis have not been recovered, three M3s of A. salvelinus are now known from Hamilton Cave, West Virginia. These teeth, as well as the others, are similar to those of the Blancan arvicoline genus Nebraskomys. These similarities support Hibbard’s (1970) suggestion that Nebraskomys was ancestral to Atopomys.
