_Measurements._--Measurements of a skull (sex undetermined) from Nicolás are as follows: condylobasal length, 77.1; zygomatic breadth, 52.9; postorbital constriction, 21.1; mastoid breadth, 43.7; length of maxillary tooth-row, 23.4; breadth of M1, 7.1. _Records of occurrence._--Two specimens examined from Nicolás, 56 km. NW Tula, 5500 ft. =Conepatus leuconotus texensis= Merriam Eastern Hog-nosed Skunk 1902. _Conepatus leuconotus texensis_ Merriam, Proc. Biol. Soc. Washington, 15:162, August 6, type from Brownsville, Cameron Co., Texas. _Distribution in Tamaulipas._--State-wide, except western part. Three specimens are assigned to this species on the basis of the breadth of M1. In comparison with skulls from the type locality, those of Tamaulipan specimens are slightly smaller and narrower. _Measurements._--Some cranial measurements of a male adult (old) from ten miles west and two miles south of Piedra are: condylobasal length, 79.0; zygomatic breadth, 52.3; postorbital constriction, 22.0; mastoid breadth, 44.2; length of maxillary tooth-row, 24.4; breadth of M1, 9.3. _Records of occurrence._--Specimens examined, 2: La Pesca, 1; Ejido Eslabones, 10 mi. W, 2 mi. S Piedra, 1200 ft., 1. Additional record: Near El Mulato (Dice, 1937:250). =Felis concolor stanleyana= Goldman Puma 1938. _Felis concolor stanleyana_ Goldman, Proc. Biol. Soc. Washington, 51:63, March 18 (renaming of _F. c. youngi_ Goldman, Proc. Biol. Soc. Washington, 49:137, August 22, type from Bruni Ranch, near Bruni, Webb Co., Texas). _Distribution in Tamaulipas._--Restricted to mountains of state. The two specimens examined are skulls only, which were picked up in the field. In general the measurements are like those given by Goldman (1946:233) for the males of _Felis concolor stanleyana_. But the skull from Miquihuana yielded measurements that suggest intergradation between _F. c. stanleyana_ and _F. c. azteca_ of the western mountains of Tamaulipas. _Measurements._--Two skulls, one from Miquihuana and the second from 9-1/2 mi. SW Padilla, yield measurements as follows: greatest length, 214.0, 213.0; condylobasal length, 195.0, 190.0; zygomatic breadth, 146.0, 140.1; height of skull (frontals to palate), 70.0, 72.4; interorbital constriction, 41.6, 41.4; breadth of nasals (at posterior union between premaxilla and maxilla), 20.1, 17.9; length of maxillary tooth-row, 62.7, 63.3; crown length of P3, 23.3, ----; breadth of P3, 11.9, 12.2; anteroposterior diameter of upper canine, 15.1, 15.3. _Records of occurrence._--Specimens examined, 2: 9-1/2 mi. SW Padilla, 800 ft., 1; Miquihuana, 6400 ft., 1. Additional records: Matamoros (Goldman, 1946:234); Zamorina (Hooper, 1953:4). =Felis onca veraecrucis= Nelson and Goldman Jaguar
