SUBSPECIES OF THE SPECIES GEOMYS BURSARIUS
If Geomys lutescens major Davis is correctly judged to intergrade with Geomys bursarius majusculus Swenk, the name for the full species will be Geomys bursarius because bursarius is the oldest name among those available. Some new combinations of names are required. According to our present understanding, the eleven kinds of pocket gophers named below are properly to be arranged as subspecies of the species Geomys bursarius:
Geomys bursarius bursarius (Shaw). Type from unknown locality in Upper Mississippi Valley.
Geomys bursarius majusculus Swenk. Type from Lincoln, Lancaster County, Nebraska.
Geomys bursarius hylaeus Blossom. Type from 10 mi. S Chadron, Dawes County, Nebraska.
Geomys bursarius levisagittalis Swenk. Type from Spencer, Boyd County, Nebraska.
Geomys bursarius vinaceus Swenk. Type from Scottsbluff, Scotts Bluff County, Nebraska.
Geomys bursarius lutescens Merriam. Type from Sandhills on Birdwood Creek, Lincoln County, Nebraska.
