Conventional taxonomic techniques using color, external, and cranial measurements are not adequate for identification and determination of distribution for chipmunks in northern California and southcentral Oregon. In the past, Tamias amoenus has been confused with Tamias speciosus and Tamias senex has not been clearly distinguished from Tamias quadrimaculatus. Genital bones of each species are diagnostic and, along with statistical analysis of measurements, provide a start toward correction of errors in taxonomy and distribution of these four species.
