e from Metlaltoyuca, Pueblo,
Mexico.)

_Specimen examined_, 1 from 70 km. [by highway] S Ciudad
Victoria and 2 km. W El Carrizo.

_Remarks._--This immature male is paler than specimens of _O. r.
rostratus_ from the state of Veracruz. This locality extends the known
range of this species northward a distance of approximately 100 miles.
Previously it had been recorded from only as far north as Alta Mira,
Tamaulipas (Goldman, N. Amer. Fauna, 43:54, September 23, 1918). This
specimen was trapped on February 16 in a rodent runway in dense grass
in a fallow cane field.

~Oryzomys fulvescens engraciae~ Osgood

Fulvous Rice Rat

_Oryzomys fulvescens engraciae_ Osgood, Jour. Mamm., 26:300,
November 14, 1945. (Type from Hacienda Santa Engracia,
northwest of Ciudad Victoria, Tamaulipas, Mexico.)

_Specimens examined_, 5 from 70 km. [by highway] S Ciudad
Victoria and 2 km. E El Carrizo.

_Remarks._--These specimens are referred to _O. f. engraciae_ on the
basis of their pale color and narrow interorbital space. They were
taken in runways in dense grass in fallow cane fields.

~Sigmodon hispidus toltecus~ (Saussure)

Hispid Cotton Rat

[_Hesperomys_] _toltecus_ Saussure, Revue et magasin de
zoologie, _ser._ 2, 12:98, 1860. (Type from mountains of
Veracruz, Mexico.)

_Sigmodon hispidus toltecus_ Bailey, Proc. Biol. Soc.
Washington, 15:110, June 2, 1902.

_Specimens examined_, 23 as follows: 36 km. N and 10 km. W
Ciudad Victoria, 1 km. E El Barretal, on Rio Purificacion,
1; 70 km. [by highway] S Ciudad Victoria and 2 km. W El
Carrizo, 22.

_Remarks._--Among named kinds of _Sigmodon_ this series most closely
approaches _S. h. toltecus_ to the southward. The specimens are
slightly lighter in color of the upper parts than are examples of this
same subspecies from 8 km. NW of Potrero, Veracruz, but in other ways
are similar. The single specimen from 36 km. N and 10 km. W Ciudad
Victoria is a skull only, but seems closest to _S. h. toltecus_. As is
often the case with collections of _Sigmodon_, this series contains
mostly immatures.

Cotton rats were found abundantly in cultivated areas. Local farmers
stated that these rats were destructive to sugar cane by girdling the
stems one and one-half inches above the ground.
