Accepted name, Mammal Species of the World 2005

The name occidentalis was formerly applied to this species (e.g., Hall and Cockrum, 1953), but populations north of the Columbia River, which include occidentalis and caurinus, have been reassigned to M. gapperi (Cowan and Guiguet, 1965; Johnson and Ostenson, 1959). See Alexander and Verts, 1992 (Mammalian Species, 406).
