Murray 1948 Myotis yumanensis Apr 29 San Ignacio, 500 ft., Baja California Two were found in a stone walled room adjoining the mission, at about 10:30 PM, where they had come to hang up. Apr 30 Same location Two were brought in by soldiers which they had caught in one of their rooms. We looked in a high room with stone walls and roof. Several were flying around after being disturbed, and probing in the narrow cracks of the ceiling turned out several more. Some were shot and some netted. The total catch was 15. These were put up by Dr. Benson. May 2 Mulege', 25 ft., Baja California We heard squeaks coming from the roof of a porch behind the government building here. Found numerous bats in a crack between two 2x12 beams side by side supporting the wooden roof. The crack was about 1/2 in. wide. Took close to 45 with quite as number more getting away At dusk went up to the prison on the hill and watched for bats flying out. Here managed to net 2. Of the total catch, only 2 were males.
