The big pocket gopher is a large burrowing rodent of the highlands of eastern Mexico. It digs its own tunnels and has a thick, black coat suited to the cool uplands.
It has a stout, tubular body and short, powerful legs with large claws. Its coat is thick and black, its eyes and ears are small, and its lips close behind its projecting front teeth to keep soil out.
It lives in self-dug burrows and uses montane forests where conifers and broad-leaved trees grow together. The account reports that it is seldom found where lower-elevation land has been converted to agriculture.
