"Greer, H. 1989 July 18 (continued) clipped 3rd vertical ant. to oval plate, on snake's left) to measure and otherwise examine her. Ardell got her up in a tube w/out difficulty. Noted two old scars, one anterior on left side neck, the other on L side of posterior body - the latter w/ obvious broken ribs. In the afternoon Alejandros and walked to Camino Cential 1300 m and spent some time off trail in what seemed like excellent Lacerta habitat. We went out CCC and back CCH, saw only a possible Masticodygas or Dendrophidion that escape under a still palm. At 1930 hrs Carol Farnetti led me to an adult ? Bothrops asper (1700 + 234 mm, 2.05 kg) coiled beside the trail at CES ~100m. She was perpendicular to and facing the trail, w/ head out over coil and parallel to ground - very nicely aimed at the roadwall. Had to hook her into a can by myself (Ardell and Alejandro elsewhere), and once she got into the woods a few meters, afterwards I led 10 students of a UCB Botanical Garden course on a nightwalk to SOC ~500, then to Cantarana - saw only 2 sleepy Norops limifrons on leaves, and frogs. July 19 after lunch we anesthetized and examined the second ? B. asper (clipped 4th vertical, on snake's left) - she started up the tape and then shot up almost to the top before I grabbed her! We noted no external injuries, but her left fang was broken several mm above the tip.
