Antrozous pallidus pallidus (LeConte). 

 Pallid Bat. 



A small company of bats, which proved to be of this species, 

 was discovered in the wall of a butte near Qninn River Crossing 

 (4100 feet) on May 18. The pallid bat is said by Miller (1897, 

 p. 43) to inhabit the Lower Austral zone. The present record is 

 very definitely from the Upper Austral, and so is significant in 

 this connection. The same author examined specimens from 

 Amargosa Desert, in southern Nye County, and from the "Tim- 

 pahute" (or Tem Piute) Mountains of Lincoln County. These 

 stations are both in southern Nevada. Our captures in northern 

 Humboldt County establish the northernmost record of the 

 species known to the writer. 



Bats were heard squeaking in a small crevice in a perpendicu- 

 lar wall of lava twenty-five feet from the base of the cliff, the 

 opening of which was about eight inches in width. Directly below 

 the opening there was a small white streak of excrement, but 

 other than this there were no visible signs of its being occupied. 

 A charge of light shot was fired into the crevice and after five 

 minutes about ten bats came tumbling out, still squeaking. They 

 flew about the cliff in a bewildered manner, finally disappearing 

 into near-by cracks.
