Michigan, no. 420: 1, June 28, 1940; Hibbard, Trans. Kansas Acad. Sci., vol. 47, p. 75, 1944. _Type locality._--Lamar, Prowers County, Colorado. _Distribution in Kansas._--Extreme southwestern part of state, northward certainly to Hamilton County and south certainly to Morton and Seward counties. _Description._--A yellowish-cinnamon colored animal, with body of medium size, zygomatic plate of maxilla deep and mastoid process small. _Comparisons._--Differs from _Geomys bursarius industrius_ in slightly lighter color; occiput not strongly inclined anterodorsally. From _G. b. lutescens_, _jugossicularis_ differs in less buffy coloration and deeper zygomatic plate of maxilla. _Remarks._--_G. bursarius jugossicularis_ and _G. bursarius industrius_ intergrade in the southern part of Meade County. Some specimens from this area show a coloration resembling that of _G. b. jugossicularis_; nevertheless, one specimen from Morton County has the occiput anterodorsally inclined as in _G. b. industrius_. Specimens examined from Hamilton County correspond closely to _G. b. jugossicularis_; they agree with it both in color and in cranial characters. _Specimens examined._--Total number, 20, distributed as follows: _Hamilton County_: 1 mi. E Coolidge, Conard Farm, 4. _Morton County_: 12 mi. NE Elkhart, 2; Cimarron River, 12 mi. N Elkhart, 4; no locality more precise than county, 6. _Seward County_: 1 mi.
