| Pocket gophers dig shallow tunnels and use them to feed on the roots of tuberous plants. They also eat seeds and other plant matter. The "pockets" are cheek pouches they can stuff with food.
Alcorn's Pocket Gopher is known only from a small area in the mountains in Jalisco, Mexico. Another species of pocket gopher, Cratogeomys tylorhinus, lives in the same pine and oak forests, but apparently has different food preferences digs to different depths, so the two coexist without competing.
The jury is still out as to whether Pappogeomys alcorni deserves its status as a species or whether it is a subspecies of the more widespread P. bulleri.
Total Length: 147-165 mm; Tail: 63-78 mm
