text: Although the tail is uniformly gray to dark brown in most rats (sometimes nearly black), a few species show one of two bicoloured patterns: brown on the tail’s entire upper surface with a paler tone or pure white on the undersurface, as in the Himalayan field rat (R. nitidus) and the Turkestan rat (R. turkestanicus), or brown all around the basal third to half of the tail with the rest uniformly white, as in Hoogerwerf’s rat (R. hoogerwerfi) and the white-tailed rat of Sulawesi.
