Mittoo, a country of central Africa, between the Roah and Rohl rivers, and between lat. 5° and 6° N., bounded N. by the territory of the Dinka and S. by that of the ISTyam-nyam. The most northerly group of tribes is that of the Mittoo proper; the other tribes are the Madi, the Madi-Kaya, Abbakah, and Looban. Tattooing is practised only among the men. Both sexes wear iron and copper ornaments and trinkets of every sort; they have a great partiality for chains, for fastening objects to their bodies, and their inventive skill in armlets and rings for the ankles is remarkable. Thick chains of iron on the neck are signs of fashion and wealth, and the ambitious often wear four at a time. The country is fertile, especially between lat. 5° and 5° 30' N., on the upper Roah and Wohko, and various cereals, tuberous plants, and oily and leguminous fruits are produced with little labor. They eat the flesh of dogs, and possess goats and poultry, but have no cattle, and are hence contemptuously called Byoor or savages. They use the bow and arrow and spears, but not shields.

They have been lately subjected to the authorities at Khartoom, and attempts have been made to employ them as "bearers," or attendants on military and trading expeditions, but with little success, owing to their general debility. - See Schweinfurth's "Heart of Africa" (2 vols., 1874).
