From Best et al. (1990): "Ammospermophilus harrisii differs from other similar-sized ground squirrels by its grayish dorsum and tail and by the presence of one white stripe along both sides of the body from shoulder to rump (Caire, 1978). It is distinguished from other members of the genus by the mixed black and white undersurface of the tail; other Ammospermophilus have a white undersurface of the tail (Hall, 1981). The percentage of light reflected from the mid-dorsal surface, for various wavelengths, is less for A. harrisii than for either A. leucurus or A. interpres (Findley et al., 1975). A. harrisii is distinguished from A. leucurus by pelage color (usually darker and grayer), and especially by the banding pattern on the undersurface of the tail (salt and pepper gray compared to white surrounded by one black band in A. l. leucurus). Cranially, the two are similar, but A. harrisii has slightly larger auditory bullae (Hafner, 1981)."
