In our recently published checklist, we mislabeled one of the species of lizards in Figure 6. In error, we listed Figure 6D as a Chihuahuan Spotted Whiptail (Aspidoscelis exsanguis) instead of the correct identification as a Little Striped Whiptail (Aspidoscelis inornata). Additionally, on 6 February 2018 (the date this manuscript was published), we received a photographic voucher of an Eastern Patch-nosed Snake (Salvadora grahamiae) from the lechuguilla-beargrass association on the top of a mesa in the Sierra Vieja (TNHC 107584), reducing the number of species not detected from the historic 1948 survey from three to two.
