Greene, H. 1990 June 20 (continued) an adult Micrurus nigrocinctus (♂,555+96mm, 51.6g) crawling off the trail at ≈SQR 200 m. When I pinned the snake w/ a foot, it thrashed, coiled and waved the tail, and bit rapidly and repeatedly. At 2040 hrs. Billie spotted a smaller adult M. nigrocinctus in the successional plots, but I was unable to pin it before the snake rapidly crawled out of sight in dense vegetation. In both cases the bright tricolored pattern was obvious and I did not experience flicker-fusion of the bands. At 2119 hrs. Dave found an adult Septemaria septentrionalis crawling at ≈3 m up in the large open tree ≈1/3 into the Cartasana Swamp from the W. end, S. of the board- walk. Snake was crawling slowly along a limb (≈ same diameter as snake), tongue flicking w/ head against limb. At 2125 I found a gravid ♀ I. septentrionalis <1 m above water near the W. end of the swamp, ascending a ≈15 an diameter tree on which there was an arboreal Tarantula at ≈ 3m. The snake was crawling in part on vine that ascended the trunk. When handled she thrashed and smelled very foul. June 21 Dave and Billie found a Rhadinaea decorata ≈0600 hrs on the path between the lab clearing and the Old River Station (4.8g, 212+136 mm). At 0700hrs two workmen showed me a Bothrops asper they found in the grassy lab clearing, under an object (22 g
