COMMENTS: Reviewed by Egoscue (1979, Mammalian Species, 122) and McGrew (1979, Mammalian Species, 123, as V. macrotis ). Revised by Waithman and Roest (1977) and Dragoo et al. (1990). Blair et al. (1968), Lechleitner (1969), Bueler (1973), and Dragoo et al. (1990) considered macrotis and velox conspecific. Packard and Bowers (1970), Rohwer and Kilgore (1973), and Thornton and Creel (1975) (who found hybrids between velox and macrotis but concluded they were of reduced viability) retained both as species.
