Hesse, H. 1988 August 11 (continued) wounds for both of us. I hooched the snake out, back up onto the road, and into the bucket. The animal appeared very stout so I thought perhaps it was a gravid ♀ and/or contained a large prey item. Dave and Billie Hardy arrived ≈ 1300 hrs, and Dave and I measured the snake: a ♂ w/ no palpable prey, 1.85 kg, tail 97mm, total length ≈ 1.42 m - a large diamondback by local standards. Every time I worked the snake, it inflated, crawled rapidly away and when restrained formed a tight S-coil and occasionally struck. It also muscled heavily, but I never saw any cloacal discharge. Yesterday Ed Hesse (former UCB grad student) told me he found a DOR Hypsiglena torquata in mesquite E. of Portal that contained a Holbrookia. Dave and I rode hunted from Portal to the Sistrums area and made five passes over the ≈5 mile stretch that seems best: we got four live snakes, one each Thamnophis marciams (exaggerated S-coil, striking, and foul cloacal discharge), Crotalus scutulatus, Rhinocleitus lecontei (thrash cloacal discharge), and Sistrurus catenatus (immobile, but later rattles for long stretches wherever I approached the cage). Driving back we released a large (≈1m) Crotalus also that was just crawling onto the road.
