Checklist of Mammal Species Classification at the species level follows "Mammal Species of The World," 2nd ed., 1993, by D. E. Wilson and D. M. Reeder; that at the subspecies level "The Mammals of North America," 2nd ed., 1981, by E. R. Hall. English names refer to the species as a whole, not individual component subspecies. If a species or subspecies is not widespread on the coastal slope of San Diego County, its range is indicated briefly. For more details on the distribution and status of terrestrial mammals, see "An Annotated List of the Mammals of San Diego County, California" by S. I. Bond (Transactions of the San Diego Society of Natural History 18:229-248, 1977), available at the San Diego Natural History Museum. **Double asterisks specify that the mammal's occurrence
in San Diego County is supported by specimens in the San Diego Natural
History Museum. |
