Greene, H. 1990 December 13 piece of log on a large bare red earth 44ha mound; (continued) When I lifted the log, the rodent was in the opening to a hole and ran out -- made me think of the steel bstein (and sightings?) of Lampropeltis triangulum in an alter mound, because that snake eats Heteromy here. Roland ? (Richmond, California - insects) saw a snake this AM that from his description had to be an adult Mastigodryas melanolomus, or a trail. Went to San Jose via bus in the afternoon, to have dinner w/ the Foydens and, coincidentally, Jack Lurgino. December 14 Returned to La Selva via the OTS car. Blake and Melissa (who will leave this PM) saw frog eggs on a leaf in the Cantarana Swamp last night, and a workman told me he saw a Bothrops asper yesterday in the Ribezeno trail. This AM alternately bright sun & rain. After lunch walked through the Cantarana and out to SOR 700 m to check the swamp below the big hollow Dipterix tree. At 1425 h a neonate (7g, 295+103mm?) Mastigodryas melanolomus crossed the sidewalk just W. of the Cantarana boardwalk - it crawled rapidly, drew the head back into an almost Pseusto-like S-coil when seized, bit and hung on to my finger. Found where an egg mass of Agalychnis callidryas had recently disappeared & where Blake told me to look -- at the "14 sign" 1.5m above boardwalk on the outer tip of a live figus leaf (Deborah Clark tells me this fig plant individual has been found nowhere else on the property
