Vernacular Names:—_Serolomootlooque_ of the Bakalahari on the Limpopo (_Cumming_); _Babala_ of the Anyanga, _Mbawala_ of the Agawa, _Imbabala_ of the Angoni, and _Mpatu_ of the Ahenga, and _Anyika_ in British Central Africa (_Crawshay_); _Mpongo_ in Kinyamwesi (_Böhm_); _Mbawara_, _Mbala_, or _Mbawala_ in Kisuaheli; _Dol_ of Somalis (_Swayne_). The typical form of this species is very nearly allied to the Bushbuck of the Cape Colony (_T. sylvaticus_), but is more strongly marked with white. Colour variable. Adult bucks sometimes nearly black or brownish grey, without traces of stripes and spots; sometimes marked with a few faint stripes and a few spots. Females and immature males are redder in colour than adult bucks, and generally weakly striped and spotted. _Hab._ From the Limpopo River across the Lower Zambesi to Nyasaland, and thence northwards to British East Africa and Somaliland.
