The Western patch-nosed snake, Salvadora hexalepis, is a nonvenomous colubrid snake found in southwestern U.S.A, and northern Mexico.
Adults are, on average, 20-46 inches long (record 58 inches), and have a distinctive, thick scale curved back over the top of the snout, and free at the edges. Four subspecies are recognized, all of which are yellowish with blackish lateral stripes in various arrangements. The dorsal scales are smooth, and the anal plate is divided.
The Western patch-nosed snake inhabits the arid deserts in its area. It feeds upon lizards, snakes, reptile eggs, and small rodents.
4-10 eggs are laid during spring or early summer and hatch in August through September.
