Show 1874.] SIR V. BROOKE ON A NEW GAZELLE. 141 2. On a New Species of Gazelle living in the Society's Menagerie. By Sir VICTOR BROOKE, Bart., F.Z.S. [Received January 14, 1874.] (Plate XXII.) The Society has lately received from Muscat* a pair of Gazelles (male and female), which differ distinctly from the Gazella arabica of Hemprich and Ehrenberg, of South-western Arabia. This species, at the time I read m y paper on this group (P. Z. S. 1873, p. 535), I believed to be the only representative of the genus Gazella found in Arabia to the south of 28° N . lat. Horns of Gazella arabica. Instead of the massive, nearly straight, non-lyrate horns of Gazella arabica (see figure)'^, the horns of the Muscat Gazelles are rather slender, compressed from side to side, and distinctly lyrate, their points being turned boldly forwards and inwards, the form being thus excluded from the non-lyrate subsection b' of m y analytical list (I. c. p. 537), which contains Gazella arabica, and placed in the subsection a', which contains the species with lyrate or semi-lyrate horns. In their general appearance, also, the Muscat Gazelles differ * [The male was presented by Major C. B. Evan Smith, 15th August, 1873. The female was deposited by Mrs. Harris,|26 September, 1873.-ED.] t See also the specimen from Mocha figured by Mr. Blanford (Greol. and Zool Abyss, p. 261, pi. i. fig. 3). |
