Publ. Mus. Zool., Univ. Michigan, 77:140, January 16.
1914, _Reithrodontomys mexicanus mexicanus_, A. H. Howell,
N. Amer. Fauna, 36:70, June 5. Not _Reithrodontomys
mexicanus_ (Saussure), being instead of J. A. Allen,
1895:135, which in part equalled _Reithrodontomys fulvescens
difficilis_.
_Distribution in Tamaulipas._--Known from two localities,
but probably occurs in all tropical areas in south part of
state.
As noted before, J. A. Allen (1891:223) reported specimens from Rancho
Santa Rosa as _Ochetodon mexicanus_, but he used this name for the
species now known as _R. fulvescens_.
The specimen examined, previously reported by Jones and Anderson
(1958:447), represents the northernmost occurrence of the species.
_Records of occurrence._--One specimen examined from Rancho
Pano Ayuctle, 6 mi. N Gomez Farias, 300 ft.
Additional record: Rancho del Cielo, 3500 ft. (Hooper,
1952:144).
