Lump-nosed Bats are found in tlie deserts, valleys and 

 foothills of California and eastward to Colorado and Texas. They 

 are common. They are summer residents in this State, but prob- 

 ably a few winter in warm localities. I have a specimen taken 

 at San Diego in March. Another taken April 25th, contained 

 one fcetus. They are on the wing before the twilight is gone. 

 They appear to inhabit caves.
