In studying the kinds of mammals known from Kansas, I had occasionto examine a series of Perognathus flavus from the westernpart of the state. Comparisons of these specimens with topotypesof named subspecies revealed that the specimens from Kansas belongto a heretofore undescribed subspecies which ranges throughwestern Nebraska, eastern Colorado, western Kansas, and westernOklahoma. 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 betweenPinkish Buff and Cinnamon-Buff (capitalized color terms after Ridgway,Color Standards and Color Nomenclature, Washington, D. C., 1912), sparselymixed with black hairs; the effect at a distance of eight feet, is between ClayColor 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 andmastoidal regions much enlarged; interparietal transversely narrow.
Comparisons.—From topotypes of P. f. flavus from El Paso, El Paso County,Texas, P. f. bunkeri differs as follows: Averaging larger in all cranial measurementstaken except in occipitonasal length, which is approximately the same,and in interparietal width, which is less; color more buffy, with fewer blackhairs dorsally. From topotypes of P. f. piperi from 23 miles southwest of Newcastle,Weston County, Wyoming, P. f. bunkeri differs as follows: Smaller infrontonasal length, mastoidal breadth, and length of auditory bulla; color morebuffy, with fewer black hairs dorsally. From topotypes of P. f. sanluisi fromnine miles east of Center, Alamosa County, Colorado, P. f. bunkeri differs asfollows: Averaging larger in all cranial measurements taken except interparietalwidth, which is smaller; color lighter and more buffy.
Remarks.—This is a brightly colored subspecies of Perognathusflavus, with less black dorsally than any adjacent one. The lateralline is well marked. Three young adult specimens taken fromWakeeney, Trego County, Kansas, are much brighter than otherspecimens from Kansas. The five specimens from Greeley, WeldCounty, Colorado, are much darker dorsally, like P. BU KİTABI OKUMAK İÇİN ÜYE OLUN VEYA GİRİŞ YAPIN!
