Raymond Hall When preparing distribution maps for a revised list of the Mammals of Kansas it became apparent to me that pocket mice of the species _Perognathus flavescens_ from south-central Kansas and adjoining parts of Oklahoma were without a subspecific name. The new subspecies is named and described below. =Perognathus flavescens cockrumi= new subspecies _Holotype._--Female, subadult (P4 moderately worn), skin with skull, No. 13045, Univ. Kansas Mus. Nat. Hist.; 4-1/2 mi. NE Danville, Harper Co., Kansas; December 1, 1939; obtained by Sam Tihen; original No. 99 of J. A. Tihen. _Range._--South-central Kansas south at least into Dewey County, Oklahoma. _Diagnosis._--Size small; upper parts Ochraceous-Buff (capitalized color terms after Ridgway, Color Standards and Color Nomenclature, Washington, D. C., 1912) heavily suffused with black; postauricular patches and a band 8 mm wide on each side Ochraceous-Buff; subauricular spot, underparts, and forefeet white; hind feet slightly dusky; tail brownish above and white below. Skull small; tympanic bullae small; rostrum wide; skull indistinguishable from that of _P. f. flavescens_ from the same latitude in western Kansas.
