_Metachirus fuscogriseus pallidus_ Allen, Bull. Amer. Mus.
Nat. Hist., 14:215, July 3, 1901. (Type from Orizaba,
Veracruz, Mexico.)
_Philander opossum pallidus_ Dalquest, Occ. Papers Mus.
Zool., Louisiana State Univ., No. 23:2, July 10, 1950.
_Specimens examined_, 3 from 70 km. [by highway] S Ciudad
Victoria and 2 km. W El Carrizo.
_Remarks._--These three specimens have proportionately longer tails
than typical _P. o. pallidus_ from central Veracruz; total length and
length of tail of two adult males are 575, 295, and 568, 290
respectively.
This marsupial has been previously unrecorded from Tamaulipas or from
so northward a locality. The four-eyed opossum evidently ranges
northward along the east face of the Sierra Madre Oriental within the
humid division of the Upper Tropical Life-zone. These animals, all
males, were taken in steel traps baited with the bodies of skinned mice
or birds. Sets were made along well-used trails leading from a densely
vegetated arroyo into a corn field through openings in a fence of
roughly piled logs. The elevation of this locality is approximately
2500 feet.
