Many rodents that are adapted to arid conditions--pocket mice, harvest mice, grasshopper mice, deer mice, kangaroo rats, and ground squirrels--occur in the same regions as Jones's Pocket Gopher in western Texas and eastern New Mexico, but only the pocket gophers (family Geomyidae) have a fossorial (that is, underground) lifestyle. Jones's Pocket Gophers are very difficult to distinguish from four other pocket gopher species without genetic and geographic data.
