Evotomys gapperi ochraceus Miller. 



Evotomys gapperi ochra.ceus Miller, Proc. Bost. Soc. Nat. Hist., vol. XXVI, 

 p. 193, March 24, 1894. 



Type locality. Mount Washington, New Hampshire (Alpine Garden, at 

 5400 feet altitude). 



Geographic distribution. The White Mountains of New Hampshire and 

 (probably eastward to) Nova Scotia. 



General characters. Similar to E. gapperi, but slightly larger and much 

 duller and paler ; fur long and lax ; skull as in gapperi. 



Color. Type specimen: dorsal area faintly outlined, pale dull rusty 

 rufous, with no black hairs ; sides buffy clay color ; belly plumbeous, 

 lightly washed with dirty whitish ; feet gray ; tail bicolor, buffy below, 

 brownish above; upper part of pencil blackish ; ears well haired, upper 

 edges pale fulvous. 



Cranial characters. Skull of type not appreciably different from that of 

 typical gapperi. 



Measurements. Type, measured in flesh by Gerrit S. Miller, Jr. : total 

 length, 148; tail vertebne, 39.6; hind foot, 19. Skull of type : basal 

 length, 22 ; nasals, 6.7; zygomatic breadth, 13; mastoid breadth, 11.3; 

 upper molar series, 5. 



General remarks. This subspecies differs from typical gapperi in paler, 

 duller coloration the opposite extreme from the dark, rich carolinensis 

 which inhabits the tops of the mountains of North Carolina. Specimens 

 from Ossipee, N. H., are evidently intermediate between Qapperl and 

 ochraceus. In size they even exceed ochraceus, and in color they are 

 slightly paler than true gapperi. Specimens from Digby and James River, 

 Nova Scotia, kindly placed at my disposal by Mr. Outrarn Bangs, are 

 plainly referable to ochraceus, though with a slightly darker, brighter 

 dorsal stripe than the. type.
