XIX b. 



Nebraska Deermouse. 



Peromyscus maniculatus nebrascensis (Mearns). 

 (L. nebrascensis, of Nebraska.) 



Hesperomys leucopus nebrascensis Mearns, 1890, Bull. Am. 



Mus. Nat. Hist., II, pp. 285 and 287. 

 Peromyscus maniculatus nebrascensis Osgood, in MSS. 

 Type Locality. — Calf Creek, central Montana. 



On page 492 this race is compared with arcticus and 

 bairdi and sufficiently characterized for identification. 



As my Manitoba specimens are not typical of this form, 

 and my notes but brief and inconclusive, I shall pass it with the 

 general statement that in habits it is a Deermouse that has 

 taken to life in the open and semi-arid Plains.
