The Texas lined snake (Tropidoclonion lineatum texanum) is a subspecies of nonvenomous colubrid snake found in the southcentral United States, primarily in the state of Texas. It is a relatively common, fossorial subspecies, spending most of its time buried in leaf litter, and eating earthworms. They are typically olive green to dark brown in color, with a distinctive yellow or cream colored stripe down the center of their back. They have small heads, and small eyes. They differ from other subspecies of T. lineatum by having fewer subcaudals: 33 or fewer in females, 40 or fewer in males.
