—

Size

general characters ^{as in} Microtus (Ph;romys) Johannes

Color.

—

_Upperparts auniform fine grizzle ofcream-buff"and blackwith adistinctbrownish

wash

on

crown

and_alongmiddleofback, the general effectsuggestingKidgway's

mars-brown

and not in theleastresembling the _pallid ochraceous-buff of Microtus Johannes. Sides not so dark as back, the _grizzling less evident. ^'Underparts light cream-buff

much

clouded by^the blackish-slateundercolor. Feetdull huffy white withan evidentbrownish wash. Tailwhitish below,brownishabove, not sharply bicolor.
