(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 11th degree of south latitude. Entry: 28
