When Goldman (1938:337) named _Thomomys bottae nicholi_ from northern Arizona he referred twelve specimens from St. George, Washington County, Utah, to his newly named race. He noted that the animals from this region intergrade with _planirostris_. I have had occasion to study one-fourth of the material available to Goldman for his original description of _nicholi_. For his specimens listed as from St. George, the exact locality of capture, which is so essential in this distributional study, was not given. All of the specimens that I have seen from the Biological Surveys Collection are from the south side of the Virgin River, while St. George itself is on the north side. As noted earlier in this account there are differences between the gophers from the two sides of the Virgin River in this area. Those from the north side are intergrades between _birdseyei_, _planirostris_ and _virgineus_, while those from the south side are intergrades between _planirostris_ and _trumbullensis_. Goldman (_loc. cit._) mentioned several times that the skulls of nicholi were nearly indistinguishable from, or closely resembled those of, _trumbullensis_. Color was the only truly diagnostic character mentioned by Goldman. My study reveals the same differences and likenesses found by Goldman, but I consider color alone insufficient basis in this instance for establishing a new subspecies, and regard _Thomomys bottae nicholi_ as a synonym of the earlier proposed name, _Thomomys bottae trumbullensis_. The animals from the south side of the Virgin River, labelled as from St. George, Washington County, heretofore referred by Goldman to _nicholi_, are intergrades between _trumbullensis_ and _planirostris_ and along with other specimens from the same place are referable to the latter race. _Specimens examined._--Total, 68, distributed as follows: _Washington County_: Danish Ranch, 5 mi.
