Specimens of the genus _Geomys_ from the late Pliocene were referred to the large _Geomys quinni_ McGrew, first by Franzen (1947:55) and later by Hibbard and Riggs (1949:835) and Hibbard (1950:171). _Geomys quinni_ has been obtained from the Fox Canyon locality and Locality 3 of the Rexroad local fauna. At Locality 3, both _Zygogeomys_ (cf. _minor_) and _Geomys quinni_ have been found together, but _Geomys quinni_ can be distinguished by its much larger size and the advanced enamel pattern of the cheek teeth (see systematic accounts beyond). All age classes are represented among the specimens of _Geomys quinni_; therefore, it seems unlikely that the smaller gophers referred to _Zygogeomys_ are actually the young of _Geomys quinni_. Hibbard (personal communication, May, 1966) informed me that specimens of _Geomys_ from the late Pliocene (Fox Canyon and Rexroad Locality 3) are erroneously referred to _G. quinni_. According to Hibbard, this material represents instead two distinct undescribed species, descriptions of which have been submitted by him for publication. Allocation of late Pliocene specimens of _Geomys quinni_ to other species will restrict _quinni_ to the early Pleistocene. _Cratogeomys bensoni_ Gidley (1922:123) was of medium size. The name was based on an upper incisor bearing a single median sulcus and an associated lower jaw containing all of the cheek teeth from the Benson local fauna, Cochise County, Arizona. Additional lower jaws carrying various teeth also were recovered. The specimens might just as well have been assigned to the genus _Pappogeomys_ since the lower dentitions of all the genera of the tribe Geomyini have the same enamel pattern, and the subgenera _Pappogeomys_ and _Cratogeomys_ have upper incisors with median grooves. The specimens are too fragmentary to warrant more than generic identification. Mainly because of their late Pliocene age and primitive traits the specimens are here regarded as early representatives of the subgenus _Pappogeomys_. Discovery of the upper molariform dentition would make a more precise assignment possible. Pleistocene
