1891. _Urocyon virginianus scottii_ Mearns, Bull. Amer. Mus.
Nat. Hist., 3:236, June 5, type from Pinal Co., Arizona.
1895. _Urocyon cinereo-argenteus scottii_, J. A. Allen,
Bull. Amer. Mus. Nat. Hist., 7:253, June.
_Distribution in Tamaulipas._--All of state in suitable
habitats.
The specimen from the Sierra Madre Oriental was obtained by a collector
who used a rabbit call. Leopold (1959:408) reported that the highest
elevation [about 2800 feet] at which he found gray fox in Mexico was at
Hacienda de Acuna, in the Sierra de Tamaulipas, where "dense, brushy
draws and oak openings made ideal habitat." At this place Leopold saw,
in early August, a family of foxes, four well-grown young and their
parents. Dice (1937:250) reported _U. c. texensis_ (a junior synonym of
_U. c. scottii_), as abundant in the Sierra San Carlos.
The six specimens examined do not present any significant difference in
size and shape of the skull from specimens of _scottii_ from Arizona,
except that one skull from the Sierra de Tamaulipas is smaller than the
others, suggesting intergradation between the subspecies _scottii_ and
_tropicalis_ from farther south.
