Murray 1948 Macrotera californicus Apr 16 Cerro Prieto, 20 miss W Mexicali, Baja Calif. Dr. Benson found one hung up in a small reed hut, close to an irrigation ditch and surrounded by many mesquites. The area around is farmland, just north of the mountain. The bat flew around a number of times, making no effort to escape though there were a number of gaping holes. Finally was taken in a net. Apr 29 San Ignacio, 500 ft., Baja California Searched in two stone walled rooms of the mission at 10 PM. Found two bats in each which had been hung up. A little later two more were taken. These were divided among all of us (see journal) Apr 30 Same location Again found several flying around in the rooms which we did not collect. They would hang up frequently for a few moments, each time appearing to swing up into an inverted position without a pause and hooking their feet to any part of the stone ceiling. Then would swing back and forth a few times from the momentum. May 10 San Jose de Comondin, 700 ft., Baja Calif - Netted 16 in a cave at the base of the high cliff on SW side of town.
