Heere, H. 1997 June 4 (continued) off trail in dense vegetation, 980 m. At one point I thought five people w/ headlamps were approaching us from scattered points, but they were just the largest brightest fireflies I've ever seen! Checked the next pond - 1 Sinorithis trianguligera juvenile no Pararesolutus. Ted meanwhile had gone to Vinh Yen with the Natl. Geographic folks to visit a snake market, and bought me a huge pregnant Enhydris bennetti. June 5 Mike, Mark Cuc, Natasha, and Nikolai left early to attend a wildlife release ceremony in Ba Vay, to be gone two days. Last night Ted caught an adult Trimeresurus muerosquamatus (♂ 745+174 mm, 97g) which we GT implanted under light anesthesia (≈1.5g radio, 148.716). We released him at capture site on middle loop road, ≈100 m from jet. with upper loop road, ≈1845hr. Walked down middle loop road to cisterns on old french ruin slab to collect 10 Polypedtes leucostepes. Walking back up we find a T. muerosquamatus in coil, possibly just retracted as we walked up, on edge of road at 2005 hr, 905 m. At 2100hr
