E. HESKE 1980 Journal Cerro Mozotol to Huixtla, Chiapas, Mexico Dec. cont seeing. Will wait until back in Berkeley to finally determine species on the two types. (Possibly the larger is fulvescens?) The line of traps in the forest ~500m S of camp yielded a single P. guatemalensis. Also, the ultimate humiliation of finding mouse shit on the door of an unsprung trap. Only 2 captures/60 traps – Duke caught 1 Reithrodonomys [says there was another same type as the two I caught]. David caught another Reithrodonomys of the smaller variety. Pulled all traps, had breakfast, and headed for Huixtla to begin karyotyping. Morning almost ended in disaster, as we were going to drive to the top of the mt. to get a few pictures but the car wouldn’t make it – no power. Had to back down to the campsite and turn around. Stopped briefly in Motozintla to get a new air filter + go to the market, then drove to Huixtla. Chose some good-looking trapping sites along the road, hopefully to get some Heteromys goldmani. Got a room at the same hotel (Molano), + spent the afternoon karyotyping, taking tissue, blood, + sperm samples, and preparing study skins on 3 H. nelsonii, 2 P. guatemalensis, and 1 P. boylei. That took from 4-8 (1600-2000). Went out for dinner – town all decorated for Xmas. Turned in ~2200.
