(29) Very distinct from the Ki-mbundu speech (though with connecting forms) is the Oci-herero group, which includes the Herero language of Damaraland, the Umbundu of the Bihe highlands of south Angola, the Nano of the Benguela coast, and Si-ndonga, Ku-anyama and Oci-mbo of the southern regions of Portuguese Angola and the northern half of German South-West Africa. The languages of group No. 29 probably extend as far inland as the Kwito and Kubango rivers, in short, to the Zambezi watershed. On the south they are confronted with the Hottentot languages. The Haukoin or Hill Damaras - a Negro race of unexplained affinities and apparently speaking a Hottentot language - occupy an enclave in the area of Herero speech.
(30) What may be called the Kiboko or Kibokwe (also Kioko) family of eastern Angola is a language-group which seems to offer affinities to the languages of the Upper Zambezi and to those of groups Nos. 28 and 29. It extends eastwards into the south-western portion of the Belgian Congo, and includes the Lubale of northern Barotseland and the sources of the river Zambezi, and possibly the Gangela of south-western Angola.
(31) Southwards of group No. 30 is that of the Barotseland languages, of which the best-known form - almost the only one that is effectively illustrated - is Si-luyi. To Si-luyi may be related the Mabunda of Western Barotseland. The dialects of the Ambwela, A-mbwe, Ma-bukushu and A-kwamashi are probably closely related.
(32) Next is a group which might be styled the Subiya-Tonga-Ila, though some authorities think that Tonga and Ila deserve to be ranked as an independent group. There is, however, a close alliance in structure between the languages of each of the two subsections. The Tonga subgroup would include the dialects of the Ba-tetela, the Ba-ila (Mashukulumbwe) and of all Central Zambezia. Ci-subiya is the dominant language of South-West Zambezia, along a portion of the Zambezi river south of Barotseland, and in the lands lying between the Zambezi and the Chobe-Linyante river. Subiya is one of the most archaic of Bantu languages, more so than Tonga. Both are without any strong affinity to Oci-herero, and only evince a slight relationship with the Zulu group (No. 44).
(33) The Bisa or Wisa family includes the languages of Iramba, Bausi, Lukinga, in the southernmost projection of the Belgian Congo, and the dialects of Lubisa and Ilala between the Chambezi river and Lake Bangweulu on the north, and the Luangwa river on the east and south; perhaps also some of the languages along the course of the Upper Luapula river.
(34) With it is closely allied that of the Bemba or Emba dialects. This interesting genus occupies the ground between the south-west and south coasts of Tanganyika, Lake Mweru, and the Upper Chambezi river. The Ki-bemba domain may be taken to include the locally-modified Ki-lungu and Ki-mambwe of South and South-East Tanganyika.
(35) What may be called the North Nyasa or Nkonde group comprises all the dialects of the north-west and north coasts of Lake Nyasa (such as Ici-wandia and Iki-nyikiusa) and Ishi-nyiχa of the Nyasa-Tanganyika plateau, and extends perhaps as far north west as the Fipa country (Iki-fipa), and the shores of Lake Rukwa (Ici-wungu) in the vicinity of the Nyamwezi domain (No. 11). Iki-fipa, however, has some affinities to the Tanganyika and western Victoria-Nyanza languages (groups Nos. 1 and 12).
(36) The western part of Nyasaland, south of group No. 35, is occupied by the Tumbuka section, which includes the languages of the Tumbuka, Henga and A-tonga peoples, and occupies the area between the western shores of Lake Nyasa and the Upper Luangwa river.
(37) Eastwards of No. 35 (North Nyasa group) lies the Kinga speech of the lofty Livingstone mountains, which is sufficiently distinct from its neighbours to be classified as a separate group.
(38) East of the Livingstone mountains and west of the Ruaha river, south also of the Unyamwezi domain, extends the Sango-Bena-Hehe-Sutu group.
(39) The extensive Yao genus of languages stretches from just behind the coast of the Lindi settlements in German East Africa (Ki-mwera) south-westward across the Ruvuma river to the north-east shores of Lake Nyasa (Ki-kese), and thence back to the valley of the Lujenda-Ruvuma (Cingindo), and southwards in various dialects of the Yao language to the south-east corner of Lake Nyasa and the region east of the Shire river, between Lake Nyasa, the Shire highlands and Mt. Mlanje. It is only since the middle of the 19th century that the Yao language has conquered territory to the south of Lake Nyasa. There still remain within its domain colonies of Nyanja-speaking people.
(40) Eastwards of the Yao domain, and bounded on the north by the range of that language in the Ruvuma valley and by the separate group of Ki-makonde (No. 10), ranges the well-marked Makua genus. The languages thus described occupy the greater part of Portuguese East Africa away from the watershed of Lake Nyasa. The Makua language is probably divided into the following dialects: - I-medo, I-lomwe, I-tugulu and Anguru. There are other dialects unnamed in the Angoji coast-region, where, however, strong colonies of Swahili-speaking people are settled. The southern part of the Makua domain is occupied by the Ci-cuambo of the Quelimane district.
(41) Nyanja, perhaps the most extensive group of cognate languages in the Bantu field, is principally associated with the east and west shores of the southern half of Lake Nyasa. It also covers all the valley of the Shire, except portions of the Shire highlands, down to the junction of that stream with the Zambezi, and further, the lands on both banks of the Zambezi down to and including its delta. West of Lake Nyasa, the Nyanja domain extends in the Senga language to the river Luangwa and the Central Zambezi, also along both banks of the Central Zambezi. South of the Central Zambezi, Nyanja dialects are spoken as far west as the Victoria Falls. Thence they extend eastwards over Mashonaland to the sea-coast. With this family may also be associated the languages of the Portuguese coast-region south of the Zambezi as far as Inhambane. The principal dialects of the Nyanja language are the Cinyanja of Eastern Nyasaland, Ci-peta and Ci-maravi of South-West Nyasaland to as far as the watershed of the Luangwa river, the Ci-mañanja of the Shire highlands, Ci-mobo and Ci-machinjiri of the Shire valley, Ci-sena or Ci-nyungwe of Tete and Sena (Zambezi), and Ci-mazaro of the Lower Zambezi. The Luangwa regions, as already mentioned, are occupied by the distinct but closely-allied Senga language.
South of the Central Zambezi there are Ci-nanzwa in the region near the Victoria Falls, Ci-nyai, Shi-kalaña, Ci-shuna (Ci-gomo), Ci-loze, and possibly Ci-shangwe (or Ci-hlangane) and Shi-lenge which link on to the Beira coast dialects. In the delta of the Zambezi is to be found Ci-podzo, a very distinct language, yet one which belongs to the Nyanja genus. Ci-shangane, Chopi or Shi-lenge and other dialects of the Beira and Inhambane coast-lands and of Manika have been much influenced by Zulu dialects (Tebele and Ronga).
(42) The well-marked Bechuana language group has very distinct features of its own. This includes all the Bantu dialects of the Bechuanaland protectorate west of the Guai river. Bechuana dialects (such as Ci-venda, Se-suto, Se-peli, Se-roloñ, Se-χlapi, etc.) cover a good deal of the north and west of the Transvaal, and extend over all the Orange River Colony and Bechuanaland. Se-suto is the language of Basutoland; Se-rolon, Se-mangwato, of the Eastern Kalahri; Se-kololo is the court language of Barotseland; Ci-venda and Se-pedi or Peli are the principal dialects of the Transvaal. Group No. 42, in fact, stretches between the Zambezi on the north and the Orange river on the south, and extends westward (except for Hottentot and Bushmen interruptions) to the domain of the Oci-herero.
(43) The Ronga (Tonga) languages of Portuguese South-East Africa (Gazaland, Lower Limpopo valley, and patches of the North Transvaal (Shi-gwamba), Delagoa Bay) are almost equally related to the Nyanja group (41) on the one hand, and to Zulu on the other, probably representing a mingling of the two influences, of which the latter predominates.
(44) Lastly comes the Zulu-Kaffir group, occupying parts of Rhodesia, the eastern portion of the Transvaal, Swaziland, Natal and the eastern half of Cape Colony. In vocabulary, and to some degree in phonetics, the Zulu language (divided at most into three dialects) is related in some phonetic features to No. 42, and of course to No. 43; otherwise it stands very much alone in its developments. It may have distant relations in groups Nos. 29 and 32. Dialects of Zulu (Tebele and Ki-ngoni or Ci-nongi) are spoken at the present day in South-West Rhodesia and in Western Nyasaland and on the plateaus north-east of Lake Nyasa, carried thither by the Zulu raiders of the early 19th century.
The foregoing is only an attempt to classify the known forms of Bantu speech and to give their approximate geographical limits. The writer is well aware that here and there exist small patches of languages spoken by two or three villages which, though emphatically Bantu, possess isolated characters making them not easily included within any of the above-mentioned groups; but too detailed a reference to these languages would be wearisome and perhaps puzzling. Broadly speaking, the domain of Bantu speech seems to be divided into four great sections: - (a) the languages of the Great Lakes and the East Coast down to and including the Zambezi basin; (b) the South-Central group (Bechuana-Zulu); (c) the languages of the South-West, from the southern part of the Belgian Congo to Damaraland and the Angola-Congo coast; and (d) the Western group, including all the Central and Northern Congo and Cameroon languages, and probably also group No. 2 of the Albert Nyanza and Semliki river.
