1906. Felis pardalis albescens, J. A. Allen, Bull. Amer. Mus. Nat. Hist., 22:219, July 25.
Distribution in Tamaulipas.—All of state, except part west of Sierra Madre Oriental.
Hall and Kelson (1959:961) reported from Tamaulipas two subspecies of Felis pardalis. According to Goldman (1943:379) the more northern of the two, F. p. albescens, is smaller than the more southern one, F. p. pardalis. The skull examined, of a young female, from 10 miles north of Altamira, in southern Tamaulipas, is small, smaller even than skulls of albescens from Texas used in comparison. For this reason I here assign the specimen examined to F. p. albescens instead of F. p. pardalis as did Hall and Kelson (op. cit.). Hooper (1953:4) and Dice (1937:251) report as F. p. pardalis specimens from 10 miles northeast of Zamorina and others from the Sierra San Carlos. I assume that specimens from these two places should be referred to albescens since the specimen from 10 miles north of Altamira, the southernmost locality represented in Tamaulipas, is here referred to albescens.
Measurements.—Skull, from 10 mi. N of Altamira, measured as follows: condylobasal length, 97.3; zygomatic breadth, 77.6; squamosal constriction, 50.5; interorbital constriction, 22.2; postorbital constriction, 32.1; length of maxillary tooth-row, 34.7; length of upper carnassial crown (outer side), 13.6.
Records of occurrence.—One specimen examined, from 10 mi. N Altamira.
