From _G. bursarius major_ of southcentral Kansas (for example Harvey County), _majusculus_ differs in slightly darker color, being Mummy Brown instead of Prout's Brown; size larger (in males total length more than 284 mm., hind foot 35 or more, basilar length of skull more than 42, and in females total length 265 or more, hind foot averaging 33 or more, and basilar length 40 or more).
Skull: Averaging larger in all parts measured, except that premaxillae do not extend so far posteriorly to nasals in either males or females; interorbital constriction slightly narrower in adult females; temporal ridges forming a more prominent sagittal crest in adult males (sagittal crest barely present in some adult males of _major_ from Harper County).
_Remarks._--In employing the subspecific name _majusculus_ we are following Swenk (1939:6) who on the basis of larger size differentiated the animals from southeastern South Dakota, the eastern parts of Nebraska and Kansas, and the western and southern parts of Iowa, from _G. bursarius bursarius_ to which he assigned a more northern geographic range. In the absence of comparative materials of the northern subspecies we cannot make an independent decision on the validity of _majusculus_ and recognize that if it is inseparable from _G. b. bursarius_ the latter name will apply to specimens from northeastern Kansas. We are the more uncertain about applying the name _majusculus_ to specimens from eastern Kansas because they average smaller than topotypes. Only at the northeasternmost locality in Kansas (3 mi. N Cummings, Atchison County) do specimens average as large as topotypes of _majusculus_. Farther southward they become progressively smaller in eastern Kansas, and we interpret this as intergradation with the still smaller subspecies _major_, to the southwest. The average external measurements of two adult males from Atchison County are: 321-99-35. Thirty-six miles farther south, in Douglas County, 16 adult males average 289-80-36. From Hamilton, Greenwood County, 80 miles farther southwest, nine adult males average 284-83-35. The maximum total length recorded at these three localities is: Atchison County, 342 (1 of 2 specimens), Douglas County, 308 (1 of 16 specimens), Greenwood County, 357 (in coll. of Dr. Glenn C. Rinker and 1 of 15 males of all ages involved). It will be seen, therefore, that although there is a trend to smaller average size toward the southward, the maximum of 357 millimeters total length at Hamilton exceeds the maximum of 352 millimeters recorded by Swenk (1939:3) among 86 males at Lincoln where the recorded average is largest.
