1855. _Spermophilus couchii_ Baird, Proc. Acad. Nat. Sci.
Philadelphia, 1:332, April, type from Santa Catarina, a few
miles west of Monterrey, Nuevo Leon.
1955. _Spermophilus variegatus couchii_, Baker, Univ. Kansas
Publ., Mus. Nat. Hist, 9:207, June 15.
_Distribution in Tamaulipas._--Possibly in southwestern
part; reported only from Ciudad Victoria (Howell, 1938:141).
Since Baird (1855:332) described _S. v. couchii_ and mentioned a
specimen from Ciudad Victoria that was obtained by Berlandier, no other
record from Tamaulipas has come to light. Probably the species obtained
by Berlandier was introduced at Ciudad Victoria by man.
