A New Subspecies of Ground Squirrel (Spermophilus spilosoma) from Tamaulipas, Mexico

This pamphlet is intended to be an announcement of the discovery of a new subspecies of ground squirrel, called the spotted ground squirrel. It is found throughout Mexico and the central and western United States. Characterized by a white spotted back, the spotted ground squirrel is one of the smallest squirrels found in North America. They are mainly herbivorous, but also eat insects. A burrowing mammal, the spotted ground squirrel will make tunnels to store its food, as well as shelter and hibernation quarters.
