The Pocket Gophers (Genus Thomomys) of Utah

INTRODUCTION

The history of pocket gophers of Utah begins with J. A. Allen's mention in 1874 of mounds of these animals. For them he employed the name "Thomomys rufescens?" (1874:65). Actual specimens were reported upon a year later by Elliot Coues (1875:251, 256), who used the name Thomomys talpoides for specimens from "Utah" but later in the same paper listed specimens from Provo as Thomomys talpoides bulbivorus. Even as the great variation in Utah pocket gophers has been perplexing to modern workers, so it was also to Coues seventy years ago who left the problem with the statement that animals from Provo "exhibit among themselves such variations that their labelling becomes a matter of indifference"! In the same year in another report, Coues and Yarrow (1875:112) used the name Thomomys talpoides umbrinus for animals from Provo. In 1877, Coues again referred these same animals to
