Remarks. 8S. tridecemlineatus badius occupies the southeastern 
corner of the range of the striped spermophile, and is most nearly 
related to the form occurring in Texas and Oklahoma, S. ¢rtdecem- 
lineatus texensis, differing, principally, from that subspecies in 
being larger and in having a much deeper, less pallid, coloring. 
From true S. ¢ridecemlineatus it can be told by the ferruginous 
under surface of its tail, the livelier brown of its upper parts and 
the coarser pattern of striping, marbling and spotting.
