DOR adult male on Linares-San Roberto Highway (8.6 km E of Iturbide). GTS 153 (Salmon, Bruno and Vermilya). UANL 5773. This is actually a Lampropeltis leonis (milksnake or thayeri phase). Map point is approximate. Exact is: N24 44 455 W099 50 616 (off my GPS at the time but it must have been an inaccurate reading as it does not plot correctly when converted to this format).
