The two young specimens from Santa Teresa are less than half 

 grown, but in general coloration above exactly resemble the adults 

 from Bee County, Texas. Below they are like a young house 

 mouse. The Bee County specimens, in midwinter pelage, are 

 superficially nearly pure white below, with the fur plumbeous for 

 the basal half. Above they are mouse gray strongly suffused with 

 yellowish brown, passing into pale orange brown on the sides. A 

 conspicuous feature in all of the specimens is the color* of the 

 inner surface of the ears, which is strong yellowish brown, or 

 brownish orange. 



This species has been recorded from Duval Co., Texas, by Mr. 

 Thomas,* and also from as far north as Grand Coteau, La., by Dr.
