interland of the
"Duala" Cameroon.

(21) The _Duala_ group, which on the other hand is of a much purer Bantu
type, includes the languages spoken on the estuary and delta of the
Cameroon river.

(22) The _Isubu-Bakwiri_ group of the coast-lands north of Cameroon delta
(Ambas Bay), and on the west slopes of Cameroon Mts.

(23) The Bantu dialects of _Fernando Po_ (_Ediya_, _Bateti_, _Bani_, &c.)
distantly allied to Nos 24, 2 and 13.

(24) The _Barondo-Bakundu_ group, which begins on the north at the Rio del
Rey on the extremity of the Bantu field, near the estuary of the Cross
river. This group may also include _Barombi_ and _Bas[=a]_, _Bonken_,
_Abo_, _Nkosi_ and other much-debased dialects, which are spoken on the
eastern slopes of the Cameroon mountains and on the Cameroon river
(Magombe), and thence to the Sanaga and Nyong rivers. Eastwards and
north-eastwards of this group, the languages (such as _Mbe_, _Bati_, _Nki_,
_Mbudikum_, _Bafut_, _Bayon_) may be described as "semi-Bantu," and
evincing affinities with the forms of speech in the basin of the Central
Benue river and also with the _Fan_ (No. 20).

(25) Turning southwards again from the north-westernmost limit of the
Bantu, we meet with another group, the _Mpongwe-Orungu_ and _Aduma_
languages of French Gabun, and the tongues of the Lower Ogowe and Fernan
Vaz promontory.

(26) These again shade on the south into the group of _Kakongo_ dialects of
the Loango and Sete Kama coast--such as _Ba-kama_, _Ba-nyanga_, _Ma-yombe_,
_Ba-vili_, _Ba-kamba_ and _Ka-kongo_ (_Kabinda_).

(27) The _Kongo_ language group comprises the dialects along the lower
course of the Congo from its mouth to Stanley Pool; also the territory of
the old kingdom of Congo, lying to the south of that river (and north of
the river Loje) from the coast eastwards to the watershed of the river
Kwango (and the longitude, more or less, of Stanley Pool).

(28) In the south the Kongo dialects melt imperceptibly into the
closely-allied Angola language. This group may be styled in a general way
_Mbundu_, and it includes the languages of Central Angola, such as
_Ki-mbundu_, _Mbamba_, _Ki-sama_, _Songo_, _U-mbangala_. The boundary of
this genus on the east is probably the Kwango river, beyond which the Lunda
languages begin (No. 14). On the north, the river Loje to some extent
serves as a frontier between the _Kongo_ and _Mbundu_ tongues. On the south
the boundary of group No. 28 is approximately the 1
