| Pocket mice usually have a few bristles on their lower backs, but not enough to be called spiny mice. This mouse is apparently closely related to the Narrow-skulled Pocket Mouse. Goldman's is slightly larger and has a hairier tail, with a narrower dark stripe on the top of the tail. It has only a few short bristles on its rump. In some parts of its range it is common in dry, rocky gullies; elsewhere it has been found in thorny scrub habitat, on lava flows that are well-covered with shrubs, and on rocky hillsides. Where its range and that of the Narrow-skulled Pocket Mouse overlap, Goldman's seems to be forced to dryer areas and its competitor occupies the land closer to a river or stream. There is very little information about its diet, but it is known to eat grass seeds. No fossils of either species have yet been found.
