“ Remarks.—Judging from the known specimens of this subspecies, it has the smallest geographic range of any of the subspecies in Kansas, but additional collecting in Hodgeman County and counties to the north and west of it may extend the known range in those directions; collecting in Comanche County and in adjoining parts of Oklahoma may extend the known range to the southward.
The anterodorsal inclination of the occiput in males is the one cranial character in which industrius differs from all of the subspecies with adjoining geographic ranges. ”

“ Skull: Zygomatic arch broadly and squarely spreading anteriorly; temporal impressions uniting to form a low sagittal crest in adult males, but in adult females and in young males the impressions usually remain apart; shape of interparietal varying from subquadrate in young specimens to subtriangular or triangular in adults; in some young specimens the interparietal is reduced to a minute, ovoid bone.
Comparisons.—See comparisons in the accounts of other subspecies occurring in Kansas. ”

“ 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. ”

“ Size: Large, total length averaging more than 280 mm. in males and 257 in females; hind foot averaging 35 mm. or more in males. Skull: Large; rostrum averaging more than twice as long as wide; sagittal crest high in males and barely present in females; occiput vertical when skull is laid top down; least width of braincase less than [224] distance from alveolus of upper incisor to middle of lateral border of P4 at alveolar border.
Comparisons.—From Geomys bursarius lutescens, majusculus differs as follows: Color darker, Mummy Brown to Prout's Brown instead of Buckthorn Brown. ”

“ In summer, Buckthorn Brown on upper parts with a dorsal band, especially distinct on specimens from Ellis and Trego counties; specimens from farther west lack the distinct dorsal band. Underparts Gray Drab and sometimes whitish, usually whitish in young specimens; basal color of pelage Deep Neutral Gray; fore and hind feet whitish. ”

“ Geomys lutescens lutescens, Hibbard, Trans. Kansas Acad. Sci., 47:74, 1944.
Type locality.—Sandhills on Birdwood Creek, Lincoln County, western Nebraska.
Distribution in Kansas.—Northwestern Kansas, eastward certainly to Ellis County, southward certainly to Scott County.
Description.—Animals with total length averaging no more than 272 mm.; length of vertebrae of tail averaging no more than 92; hind foot averaging no more than 35. Color: In autumn pelage, upper parts Light Ochraceous-Buff becoming Buckthorn Brown in middorsal region and there forming a faint longitudinal band ”

“ 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.
Four specimens from Salina (Debold Farm) are intermediate structurally, as they are also geographically, between G. b. majusculus on the one hand and Geomys bursarius lutescens and Geomys bursarius major on the other hand. ”
