Goldman (1910:104) regarded cinnamomea as a synonym of oro- lestes. Warren, (1942:221) maintained his earlier usage of the name cinnamomea for bushy-tailed woodrats of northwestern Colo- rado, commenting: "... I have compared my own specimens . . with a long series of oro- lestes in my collection, and they are a different shade of color from any of these, also smaller . . , and I prefer to consider this a separate subspecies from orolestes, as much different as any of my arizonae, although in a somewhat different ; The nominal race cinna- momea was said to differ from arizonae in paler color and less bushy tail. Hooper (1944: 415) revived the name cinnamomea for ani- mals from southwestern Wyoming; no com- parison was made with N. c. arizonae. Finley (1958:263) made extensive compar- isons of specimens of N. cinerea from north- western and southwestern Colorado and ad- jacent areas. No consistent differences were found between animals from the two areas. Therefore, Finley (op. cit.: 260) arranged cinnamomea as a synonym of arizonae. I have reviewed evidence presented by Finley and have repeated a number of the comparisons. I concur in the opinion that arizonae and cinna- momea are inseparable and in Colorado form a single, essentially continuous population. Hall and Kelson (1958:704) referred two specimens from north and west of Rangely to the subspecies N. c. macrodon, a race recog- nized (Kel
