E.Heske 1980 Journal San Cristobal to 3.9 mi NE Bochil, Chiapas, Mexico december Arose ~0630. Checked trapline along creek; caught 4 P.boylei. Day is sunny + clear - nowind, ~10°C but warming fast in the sun. David caught 1 P.boylei and 1 Reithrodonomys (small, looks ~8-9g; colored like a megalotis ) along the edge of forest / secondary growth near camp. Duke's lines through the forest yielded 11 P.boylei. Forest in general has high canopy of pine, secondary canopy of oak (~10m), and scattered herbaceous ground cover w/needles on floor. Ate breakfast, prepared to leave. Two of the P.mexicanus, two P.gymnotis died of cold last night. Also, 5 of the P.boylei in Duke's traps were dead. Headed in to San Cristobal to get some groceries, water. Market place is great - would love to spend a day or two here just wandering around the market and shops, but no time (Cas usual-). Water purification place not open today (Sunday); no unleaded gas anywhere either. wasted the morning driving all the way back to Tuxtla Gutierrez in search of unleaded gas with no luck. Finally had to fill it with Nova. Took the Hwy 195 North just W. of Tuxtla G., heading for a locality Duke wants to trap near Rayon. Stopped at a roadside cracked rock/gravel pile 3.9 mi NE of Bochil to set traps, as it was getting late (~1545). Area looked good at first
