Macrotus californicus Baird 

 California Leaf-nosed Bat 



One of the rooms of an adobe ruin on the Arizona side, ten miles 

 below Cibola, showed considerable bat excrement on the floor. No bats 

 could be found in the thatch above, so the place was visited in the 

 evening. No bats appeared in the vicinity until all daylight had faded. 

 Then two were -seen flj'ing about the ruins ; and by means of a lantern 

 and butterfly net, one was caught in the room referred to. This was 

 probably used by the bats merely to repair to while eating the moths 

 caught outside ; wings of the latter were strewn upon the floor. 



The specimen obtained (no. 10693) is an adult male; the date 

 April 8. 



Transmitted June 1.3, 1913.
