 kiyou County (uo. 13797), and one at Jackson Lake, Siskiyou

My otis longicrus longicrus (True) 

 Long-legged Bat 

 There is nothing quite so wasteful of ammunition as shooting 

 at bats. At Kangaroo Creek and Castle Lake we used to spend 

 the evenings until dark trying to hit the wavering, fluttering things. 

 The time for shooting was limited because the bats would not come 

 out until the light was nearly gone ; this accounts in part for the 

 few secured. Two specimens of the above species (nos. 13804, 

 13S05) were taken at Castle Lake, August 22. 



Lasionycteris noctivagans (Le Conte) 

 Silver-haired Bat 



Two specimens w 7 ere gotten at Kangaroo Creek, August 4 (nos. 

 13802, 13803) ; these are evidently young, though they were well 

 able to fly. 



Eptesicus fuscus fuscus (Beauvois) 



Large Brown Bat 



Two specimens taken at Kangaroo Creek, August 3 and 4 (nos. 

 13799, 13800), and one at Castle Lake, August 19 (no. 13801).
