Type locality.—Eight miles west of Clarendon, Donley County, Texas.
Distribution in Kansas.—Southcentral Kansas, northward certainly to Ellsworth County, westward certainly to Stafford and Barber counties and eastward to Cowley County.
Description.—Color: Upper parts varying from Brussels Brown in some specimens to nearly Prout's Brown, especially in specimens from central part of state. Top of head, and sometimes back, darker than rest of upper parts, but no well defined black stripe; underparts varying from whitish to nearly Buffy Brown; fore and hind feet and approximately distal half of tail white. Size: Large (see measurements). Skull: Sagittal crest absent in females and barely present in males; least width of braincase more than distance from alveolus of incisor to middle of lateral border of P4 at alveolar border. Length of auditory bulla (from anteroventral edge of paroccipital process of exoccipital to hamulus of peterygoid), in each sex, more than 8 mm.; occiput usually vertical when skull is laid top down; zygomatic arch broadly and squarely spreading, divergent anteriorly; rostrum averaging less than twice as long as wide.
Comparisons.—From G. bursarius lutescens, major differs in color darker, premaxillae extending slightly farther posteriorly; temporal impressions usually forming a more well-marked sagittal crest in males; ventral side of zygomatic arch, at level of jugal bone, more curved.
From G. bursarius majusculus, major differs in slightly lighter color, smaller size of body; in males, total length less than 284 mm.; hind foot 34 or less; basilar length of skull less than 42; in females total length less than 264, hind foot no more than 33, and basilar length less than 39.
