se that several tropical mammals range farther northward than
previously reported. Funds for financing the field work were made
available by a grant from the Kansas University Endowment Association.

ACCOUNTS OF SPECIES

~Didelphis mesamericana mesamericana~ Oken

Central American Opossum

_Did[elphys] mes-americana_ Oken, Lehrbuch d. Naturgesch.,
pt. 3, vol. 2:1152, 1816. (Type from Northern Mexico.)

_Didelphis mes-americana_ Allen, Bull. Amer. Mus. Nat.
Hist., 16:256, August 18, 1902.

_Specimens examined_, 2 as follows: 36 km. N and 10 km. W
Ciudad Victoria, 1 km. E El Barretal, on Rio Purificacion,
1; 12 km. N and 4 km. W Ciudad Victoria, 1.

~Philander opossum pallidus~ (Allen)

Four-eyed Opossum

_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.
