Other alternative designations for Anelytropis locality below: 0.6 miles E. of km. 110 on Hwy. 70 and 9.0 miles E. of La Boquilla on Hwy. 70 15.3 miles E. Rio Verde via Hwy. 70, San Luis Potosi, 1:00 - 2:50 pm Avery arid area on the plateau west of the Sierra Madre. Worked a south flowing gully (dry) for Cnemidophorus and found 2 Anelytropis papillosus instead. Both specimens were under a white flowered bush (flowers, fruits & leaves collected) at the leaf litter - loose soil interface on the downhill side from the main trunk of the bush They were found under. The smaller specimen was found on the west side of the gully & the larger was found on the east side. The technique employed was exactly that used in hunting for [illegible] Anniella in California - just raking away the leaf litter layer & then raking away the loose soil beneath. The larger specimen defecated a blackish substance and bit me, and both specimens wriggled violently when held in the hand. The smaller specimen was pinkish in color ventrally & brownish above. The larger specimen lacked the pink ventral color.
