168 Bangs — Little Harvest Mouse from West Virginia. 



white; ears dusky, with some reddish brown hairs on both inner and 

 outer surfaces; tail indistinctly bicolor, dusky above, grayish white be- 

 low, rather more hairy than in true R. lecontii; under fur plumbeous 

 throughout except on chin and under side of head, where the hairs are 

 whitish to their base. 



Measurements. 



Remarks. — Specimens from Raleigh, N. C. , of which there are many in 

 collections, taken by the Brimley brothers, appear to be intermediates, 

 though nearer true R. lecontii. In R. lecontii impiger the ear is much 

 smaller than in all specimens I have examined from Georgia and north- 

 ern Florida. For instance, an adult V R- lecontii lecontii taken by W. W. 

 Brown, Jr., at Pinetueky, Ga. , measures : Total length, 136 ; tail vertebrae, 

 62 ; hind foot, 16; ear from notch, 12 (in dried skin 11.5). Judged by 

 the skulls, this specimen is younger than the type of R. lecontii impiger' 

 These differences in size and proportions, combined with the differences 

 in color and the smaller and more delicate skull of impiger, serve to dis- 

 tinguish all specimens 1 have examined from extreme localities.
