Lasiurus borealis teliotus (H. Allen). 



Linden, San Joaquin county, California. 9 . June 2, 1898. 



On comparison with Eastern specimens of borealis, this specimen 

 has the under surface much paler and more of a pale buff tint. This 

 does not seem to have been noticed by Miller (North Amer. Fauna, No. 

 13, pp. 110-111) in summarizing the differential characters of the race.
