Reithrodontomys chrysopsis chrysopsis Merriam
Volcano Harvest Mouse; Spanish, Ratón Dorado
Reithrodontomys chrysopsis Merriam, Proc. Biol. Soc. Washington, 13:152, June 13, 1900, type from Mount Popocatepetl, México.
Reithrodontomys chrysopsis chrysopsis, Howell, N. Amer. Fauna, 36:66, June 5, 1914.
Range.—Patambán, 1,200 feet elevation as now known.
Remarks.—Howell (1914:68) lists nine specimens from Patambán. We have not examined these specimens. He listed at the same time seven of the specimens from Tancítaro, but we have found specimens from Tancítaro to be of another subspecies, R. c. seclusus. Accordingly, we are in doubt as to whether the mice from Patambán are subspecies chrysopsis, seclusus, or an unnamed subspecies and our use here of the name Reithrodontomys chrysopsis chrysopsis for them is, of course, provisional.
