For comparison with _G. l. major_, see account of that subspecies. _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. The existence of this unique (among adjoining subspecies) cranial character is the principal reason for according subspecific status to this animal. Although it has other characters which are fairly uniform over a considerable geographic area, these other characters, namely, Cinnamon Brown color of the upper parts and medium size of the body, after all, are conditions intermediate between those in _jugossicularis_ to the west and those in the darker and larger animals assigned to _major_ to the eastward. Considering the intermediate geographic position of _industrius_, the color and size are approximately what a person would predict by study of only the animals to the west and those to the east. Therefore, the color and size probably are indicative of intergradation between _jugossicularis_ and _major_. Still, there is the anterodorsally inclined occiput in males--a character of a unique sort--and this influences us to give subspecific status to this animal with full recognition of the fact that it is a "weak" subspecies as compared with any one of the adjoining subspecies. Hooper (1940:2) in naming as new _Geomys lutescens jugossicularis_ referred to his new subspecies a skin-only from Meade County State Park. Our more abundant material from there shows the cranial conformation to be that of _industrius_ to which we accordingly assign the specimens. However, with only a skin available, we, too, would have used the name _jugossicularis_ because the color is paler than in other specimens of _industrius_ and this paleness indicates intergradation between the two named subspecies. Specimens from Pratt County are slightly darker than _industrius_ thereby indicating intergradation between _industrius_ and _major_.
