Remarks. — This species is plentifully represented in the United 

 States National Museum collection. Its range covers a territory 

 in Mexico on the south from the State of Pueblo north to central 

 Texas (Austin on the east, and as far north as Brazos, Palo Pinto 

 County), thence west through New Mexico, Arizona, Utah (north- 

 eastern), and from southern California north to Chico in Butte 

 County and Fort Dallas, Greg. This bat has a remarkably extensive 

 range for a single species and varies only slightly in intensity of color, 

 mummy brown to Prout's brown (Ridgway 1912). These variations 

 are never localized, and dark and light examples can be matched 

 from almost any two localities.
