Serengeti-Dorobo (a nonce name) is an obscure "Dorobo" language, a few words of which were recorded in the late 19th century by Oscar Baumann.
From the little data available, the language is not obviously related to any other, though the numeral system is Nilotic.
It is not the only "Dorobo" language formerly spoken in the Serengeti.
A few paragraphs were recorded by Baumann (1894, p. 366), but without any word-by-word translations.
Most resemble those of neighboring Nilotic languages.
