THREE NEW RACES OF VESPERTILIONID 

 BATS PROM CALIFORNIA 



BY 



HILDA WOOD GRINNELL 



(Contribution from the Museum of Vertebrate Zoology of the University of California) 



During the past six years there has been accumulated in the 

 .Museum of Vertebrate Zoology a collection of eight hundred and 

 thirteen specimens of bats from within the boundaries of California. 

 Although material is still lacking from many important localities 

 within the state, there is now at hand in several instances a sufficient 

 number of specimens to show clearly the existence of certain hitherto 

 unnamed races. Three of these new races are described below. In 

 these descriptions all measurements are given in millimeters; total 

 length, tail vertebrae and foot measured in the flesh by the collector. 

 Color descriptions are based upon Ridgway's Color Standards and 

 Si'im nclat nrc (1912). 



The writer's thanks are due to Mr. Henry W. Henshaw, Chief of 

 the Bureau of Biological Survey. United States Department of Agri- 

 culture, and to Mr. John Rowley, Curator of Mammals. California 

 Academy of Sciences, for the loan of pertinent material used in 

 comparisons.
