LENDELL COCKRUM In studying the kinds of mammals known from Kansas, I had occasion to examine a series of _Perognathus flavus_ from the western part of the state. Comparisons of these specimens with topotypes of named subspecies revealed that the specimens from Kansas belong to a heretofore undescribed subspecies which ranges through western Nebraska, eastern Colorado, western Kansas, and western Oklahoma. This subspecies is named and described as follows. =Perognathus flavus bunkeri=, new subspecies _Type._--Female, adult, skin and skull; No. 11716, Univ. Kansas Mus. Nat. Hist.; Conard Farm, 1 mi. E Coolidge, Hamilton County, Kansas; 1 July 1936; obtained by F. Parks and C. W. Hibbard, original No. 894 of Hibbard. _Diagnosis._--Size large (see measurements). Color light, upper parts between Pinkish Buff and Cinnamon-Buff (capitalized color terms after Ridgway, Color Standards and Color Nomenclature, Washington, D. C., 1912), sparsely mixed with black hairs; the effect at a distance of eight feet, is between Clay Color and Tawny-Olive; lateral line between Pinkish Buff and Cinnamon-Buff; postauricular spots near Pinkish Buff; small subauricular spots white; underparts white. Skull of medium size (see measurements); frontonasal and mastoidal regions much enlarged; interparietal transversely narrow.
