The _Luena_ or _Lubale_ language only enters the north-western part of Barotseland; _Mbunda_ is spoken in separate parts on either side of the Upper Zambezi, also in the north of this state; _Lujazi_ extends from South-East Angola to the western limits of Barotse territory; and Chokwe comes in as a trading language in the extreme north. None of these North-West Zambezia languages use preprefixes. One other great Bantu Group may be met with in the northern part of Barotseland. Here there are outlying dialects of Luba and Lunda which have penetrated into Barotseland comparatively recently. The Luba tongues of South Congoland are represented by _Kahonde_, a form of South Luba illustrated in my Comparative Study under the designation of 105a. This is spoken on the North-Eastern verge of Barotseland in the basin of the Upper Kabompo river. Southern Lunda, introduced into the northern part of this territory goes under the name of “_Ma-bunda_,” the root of which—_bunda_—is the same as that of “Mbunda,” a quite distinct language of the North-West Zambezia Group allied to Luena, Lujazi, Nkoya, and Chokwe. “Bunda” is evidently a language and tribal name which in the shapes of -_bundu_, -_bundo_, and -_bunda_ haunts Angola and Western Zambezia without implying close relationship between the different forms of speech thus termed. The “Ma-bunda” dialect of Lunda may represent an older form of the latter name, which seems to be a contraction of Lu-unda for Lu-bunda. The language (No. 111) which I have styled “Western Lunda” in my Comparative Study was originally called by its discoverer, the Revd. S. Koelle, “Ru-unda,” suggesting that _Ru_- (= _Lu_-) was the familiar language prefix and -_unda_ or -_bunda_ the root. The loss of an initial _b_ is a frequent occurrence in the Lunda languages. * * * * * The distribution of tongues southward from Angola and the Congo Basin over the regions north of the main Zambezi river indicates no causes of hesitancy, no interruptions in the north-to-south progress of the Bantu peoples. But westward of the course of the Luangwa river, as far as the Barotse country extends, or at any rate as far as the main stream of the Zambezi flows, this great river seems to have been a very decided and arresting barrier in the distribution not only of African tribes and languages but of the larger or more remarkable mammals and birds.
