The specimen from Jaumave is clearly _M. f. frenata_, but the other from northwest of Altamira has many characters of the subspecies _M. f. tropicalis_ and is an intergrade between the two subspecies. In cranial features and in measurements the animal is like _frenata_. For example: least width of palate more than length of P4; distance between anterior border of auditory bulla and foramen ovale equal to the width of four (including I3) upper incisors; depth of tympanic bulla less than distance between it and foramen ovale; length of tail amounting to 82 per cent of length of head and body. The coloration is more nearly like that of _tropicalis_. For example, the region between the ears and the region behind the ears as far as the shoulders is almost black; hairs of the soles of the forefeet are of the same color as in _tropicalis_. But, width of the whitish underparts amounts to 53 per cent of the circumference of the body; in this respect the specimen is like _frenata_. I refer the specimen to _frenata_ because, to me, it is slightly more nearly like it. _Measurements._--The male from 6 mi. N, 6 mi. W Altamira affords measurements as follows: 500; 226; 53; 23; basilar length (Hensel), 49.5; breadth of rostrum, 14.3; interorbital constriction, 11.9; orbitonasal length, 15.2; mastoid breadth, 27.2; zygomatic breadth, 32.4; tympanic bullae, length, 16.8; breadth, 7.5; length of m1, 5.7; P4, lateral length, 5.4, medial, 5.8; M1, breadth, 4.6, length, 2.4; depth of skull at anterior edge of basioccipital, 14.7. _Records of occurrence._--Specimens examined, 2: Jaumave, 2400 ft., 1; 6 mi. N, 6 mi. W Altamira, 1. Additional records (Hall, 1951:347): Matamoros; Miquihuana. =Mustela frenata tropicalis= (Merriam) 1896. _Putorius tropicalis_ Merriam, N. Amer. Fauna, 11:30, June 30, type from Jico, Veracruz. _Distribution in Tamaulipas._--Tropical area in south part of state; reported only from 50 mi. south of Ciudad Victoria (Hall, 1951:366). =Eira barbara senex= (Thomas) Tayra 1900. _Galictis barbara senex_ Thomas, Ann. Mag. Nat. Hist., ser. 7, 5:146, January, type from Hacienda Tortugas, approximately 600 ft., Jalapa, Veracruz. 1951. _Eira barbara senex_, Hershkovitz, Fieldiana-Zool., 31:561, July 10. _Distribution in Tamaulipas._--Known only from Pano Ayuctle (Hooper, 1953:4). =Taxidea taxus= Badger The badger in Tamaulipas is poorly known because only a few specimens have been reported from the state. I have examined only two; one is the skull of a juvenile picked up in the sea along the barrier beach and the other is the skull of an adult male taken in a steel-trap baited with a bird body and rabbit meat. The trap was set in front of a hole in the semidesert area 12 miles south of San Carlos.
