Flores, H. 1985 12 August dropping off Howard Hawker at his home in the Avza (continued) Valley in the course of things. No rain, dark moon, warm, as before, our route was up and down (N-S) on Sandario Rd., an area of lowland desert that is particularly moist at its south end (it ends at the Ajo Rd.), alternated with trips over the Tucson Mountains via Mile Wide, Kinney, and Gates Pass Roads, turning west again at Camino de Oeste on the western outside of Tucson. Found 17 snakes and saw 2 carnivores: a fresh DOR Trimorphodon biscutatus low on the E. slopes of the Tucson Mountains (2111 hr), 2 AOR juvenile Rhinocaelus decortei, claus-phase (2032 hr, not collected, in Saguaro National Monument), 2139 hr); 2 DOR Pituophis melanoleucus (1929 hr, 2354 hr); 1 AOR yearly Crotalus ligus (2136 hr); and 1 AOR juvenile C. atrox (2132 hr) on the western slopes of the Tucson Mountains. All of the above snakes came from rocky, upland desert habitats w/ lots of Saguaros. On Sandario Rd., lowland desert, we saw (didn't collect) 4 juvenile C. atrox (2146, 2149, 2151, ~2310 hrs.), 2 adult C. atrox (2222, ~2340 hr), 3 juvenile C. scutulatus (2200, 2205, 2212 hrs), and 1 adult C. scutulatus (2227 hr). Also saw 1 Canis latrans and 1 Lynx rufus on western slopes of the Tucson Mountains. 13 August Road hunted by myself from ~1930-2200 hr in the upland desert area described above. No rain, dark moon,
