Discussion: Subgenus Reithrodontomys , fulvescens species group. Chromosomal complement (2n = 50) interpreted as primitive for the genus ( Robbins and Baker, 1980). Genetically strongly divergent from six other species of the subgenus Reithrodontomys based on cytochrome b sequences ( Bell et al., 2001). Westerly dispersion along grassy railway borders onto Llano Estacado, NC Texas, documented by Yancey and Jones (1997); also see Peppers et al. (1998) for records of northward extension in Texas. Appreciable fixed allelic differences detected among certain samples from the US and Mexico advise the need for taxonomic review of included synonyms ( Arellano et al., 2003; Arnold et al., 1983). See Spencer and Cameron (1982, Mammalian Species, 174).
