This woodrat lives in dry areas from the southern United States to central Mexico. It has a grey-brown back and white underside, is active at night, and uses nests surrounded by plants and woody debris.
Its back is grayish brown and its underside is white. It has large eyes and ears and a relatively short tail.
It is nocturnal and usually solitary. It builds large nests from plants and woody debris and may use regular paths near the nest.
In Texas, it builds a cup-shaped nest of shredded dry leaves, grass blades, and weed stems inside a pile of sticks and cactus joints.
In the Texas account, droppings are deposited in one place outside and near the midden, rather than inside it.
At Carlsbad Caverns National Park in New Mexico, one female examined on 11 May contained two fetuses.
