MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 79 



and body, heavily haired, with well-defined tuft at tip. Body above, dull, 

 yellowish-brown, in adults ; beneath, white ; tail colors to correspond ; feet 

 white. In nubiterrce, the Cloudland race, the size is not only much smaller, 

 but the color above is a sort of smoky brown in adults and the underparts less 

 pure white, '

Type locality. — Summit of Roan Mt., Mitchell Co., North Carolina. Alti- 

 tude, 6370 ft. 



Faunal distribution. — Canadian or balsam forest belts of the higher south- 

 ern Alleghanies, insensibly grading into canadensis along the middle Alle- 

 ghany ridge, from southern Pa. to southern West Virginia. 



Distribution in Pa. and N.J. — Not found in N. J. The most closely allied 

 examples of Pa. nubiterrae that I have seen were taken in southern Somerset 

 Co. They are more characteristic of the subspecies than of the typical form. 



Habits, description of species, etc. — See under preceding species. 



Specimens exa?nined. — Cambria Co., Krings, 9 ; Cresson and Summit, 6. 

 Somerset Co., Summit Mills, 20.

 series, vol. 16, p. 192. 



Type locality. — Pine Barrens of Kentucky. 



Faunal distribution. — Upper austral zone, grading into the subspecies next 

 considered {noveboracensis) , in the transition zone. These two include 

 practically all of the common lowland deer or white-footed mice ordinarily 

 met with in the New England and Middle States and the Ohio Valley. Two 

 other species somewhat overlap its range in the edge of the upper austral 

 zone, the Golden mouse {P. nuttalli),* a very distinct species, and the Cotton 



* A supposed specimen of nuttalli was recorded by Baird in his Mammals of N. America, 

 vol. 8 of the Pacific R. R. Reports, 1857, p. 468, as coming from the Falls of Schuylkill, Pa. 

 I agree with Coues that this must be a wrong identification. Baird also included a Carlisle, 

 Pa. skull under this species, but there is enough variation in leucopus to account for a re- 

 semblance in this to one of nuttalli. Baird lists it after a question mark.
