  Comment: Comments: Typically considered a subspecies of O. typus subsequent to Bohmann's (1952) monograph (e.g., Misonne, 1974; Musser and Carleton, 1993). Although their lower incisors do possess two well-defined grooves, as in O. typus, the Mount Elgon populations contrast sharply in their smaller size, dark brown pelage, and M3 with only 7 laminae. Clausnitzer and Kityo (2001) recorded the species (as O. typus) as common in afro-alpine habitats, where it exists sympatrically with O. barbouri
