Distribution in Tamaulipas.—Western part of state.
The specimen examined, a male that weighed 646 grams, was shot at night.
This species occurs only in western Tamaulipas. Hall and Kelson (1959:267, map 187) mistakenly plotted El Mulato, as being in the eastern part of the state; actually this locality is in the San Carlos Mountains of the west, near the boundary between Tamaulipas and Nuevo León.
Records of occurrence.—One specimen examined from 4 mi. SW Nuevo Laredo, 900 ft.
Additional records (Nelson, 1909:237, unless otherwise noted): Nuevo Laredo; Guerrero; Mier; Camargo; El Mulato (Dice, 1937:256); Miquihuana.
