When Mr. Rothschild separated this southern form of the Sitatunga as _Tragelaphus selousi_ in 1898 (Nov. Zool. vol. v. p. 206), he did not distinctly state the specimen from which he took the description of the adult male, but we presume it to be the above-mentioned specimen from the Barotze District (_Coryndon_), which he has kindly lent us. For the type of his female, however, Mr. Rothschild expressly designates the female now living in the Zoological Society’s Gardens. We are therefore, no doubt, correct in applying the appropriate specific name “_selousi_” to the present form. _April_, 1900. [Illustration: THE BOOK OF ANTELOPES, PL.
