Hess, H. 1992 May 26 (continued) 1/2 of his total length was extended straight, and his head rested slanted upward in the inside of an entire loop of the artery. I took photos, appropy slowly until I was crouched on hands and knees about 50 cm from his face - when he gave a very brief burst of rattle w/ no other movement. Next I picked up Barney Torbalin and Landon Concagh and at 1150 h we found Crotalus atrox #1 ~2m south of the same rot nest but under the edge of the droopy mosquite limbs - he rattled from ~1/2 km in front of me just as I spotted him. The snake seemed so distinctly more reddish Barney thought it wasn't our radiotagged animal but we confined the signal and spotted green paint at the rattle base. As I drove out of Portal for Tucson, via Paradise, checked on C. molossus # 9; now, at 1409 h, he has pulled the tail into a fairly tight symmetrical coil. May 27 Barstow, San Bernardino Co. California arrived here ~2130 h, having left Tucson this AM and had lunch w/ Dave Darrell, Bryan Sullivan, and C. Holycross at ASU-West in Phoenix. I road hunted National Trails Hwy from Indlow to Newberg Spring and picked up an adult ? Phyllodrymus decurtatus a few miles east of the RR crossing at Piagch Java Flow - only response to handling was a foul cloacal discharge and squiering.
