Mammals -- Mexico -- Tamaulipas
1933. _Felis onca veraecrucis_ Nelson and Goldman, Jour.
Mamm., 14:236, August 17, type from San Andrés Tuxtla,
Veracruz.
_Distribution in Tamaulipas._--Originally all of state; now
restricted to sparsely populated areas.
Only one cranium, from the Sierra de Tamaulipas, was examined. It is in
good condition but lacks all the teeth except P3 and P4 on the right
side. The measurements are larger than those given by Goodwin (1954:15)
for a skull from five miles north of Gómez Farías.
_Measurements._--The cranium, sex undetermined, from the
Sierra de Tamaulipas, affords measurements as follows:
greatest length, 238.0; condylobasal length, 204.0;
zygomatic breadth, 166.0; breadth of rostrum, 66.1;
interorbital constriction, 48.2; mastoid breadth, 100.7;
crown length of carnassial, 24.1.
_Records of occurrence._--One specimen examined from Sierra
de Tamaulipas, 2 mi. S, 10 mi. W Piedra.
Additional records: between Aldama and Soto la Marina
(Nelson and Goldman, 1933:237); 5 km. N Gómez Farías
(Goodwin, 1954:15).

1855. _Felis albescens_ Pucheran, in I. Geoffroy
Saint-Hilaire, Mammiferes, in Petit-Thoaurs, Voyage autor du
monde sur ... _la Venus_ ..., Zoologie, p. 149, type
locality, Arkansas.
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.
