A New Subspecies of Ground Squirrel (Spermophilus Spilosoma) From Tamaulipas, Mexico
When A. H. Howell (N. Amer. Fauna, 56:1-256, 1938) revised the North American ground squirrels, he had no specimens of the spotted ground squirrel, Spermophilus spilosoma, from Tamaulipas. Thirteen years later, Hall (Univ. Kansas Publ., Mus. Nat. Hist., 5:38, 1951) listed the species for the first time from the state when he recorded as S. s. annectens 13 specimens from the barrier beach 88-89 miles south and 10 miles west of Matamoros.
