Greene, H. 1986 2 January the cloaca was prolapsed and it expelled a thick (continued) yellow liquid. I didn't detect any odor. Walked to CES 700 m, and spent ~10 minutes at ~CES 550m searching the area where I saw two Lachesis muta in July 1987. Lastly, went to ~250mSoc and back by ~1130 hr. At 1855 hr.

I found an old lutia longicaudus scat on the rock I've often seen then on before, and the end of the Sendero Riberano. This scat contained large fish scales and parts of crustacean exoskeleton.
