Of the Antelopes there is a fairly well-marked section, distinguished by the possession of horns in both sexes, at the same time that the body is peculiarly deep at the shoulder, whilst the lengthy tail is cylindrical and tufted at the extremity. Among these there is a mane along the neck in three closely-allied species, the BLAUBOK, or Equine Antelope of South Africa, the SABLE ANTELOPE of the Transvaal and the eastern coast of Africa, and BAKER’S ANTELOPE, or the Maarif of Upper Nubia, as well as in the ORYX, which is found in many parts of Africa, the BEISA of Abyssinia, the BEATRIX ANTELOPE of Arabia, and the GEMSBOK of South Africa; whilst in the not distant ADDAX ANTELOPE of North Africa there is no nape-mane, but a slight one on the throat. [Illustration: ORYX.] In the Blaubok, which stands more than four feet and a half at the shoulder, with a glaucous, grey coat upon a black skin; in the Sable Antelope, which stands four feet and a half, being black except upon the abdomen, as well as in streaks upon the face, which are white; and in Baker’s Antelope, which stands four feet eight inches, being of a pale fulvous liver colour, the horns are two feet and more in length, and curved gently backwards, being ringed transversely except at the tips, where they are smooth. In the Oryx, the Beisa, the Beatrix Antelope, and the Gemsbok, the lengthy conical horns, although similarly ringed, are much more slender, starting backwards in a line with the face, whilst in those previously mentioned they rise at an angle from it, being straight in the Gemsbok and Beisa, very slightly curved backwards in the Beatrix, and more so in the Oryx. In the nearly allied Addax the similarly-constructed horns are gently twisted in a corkscrew manner. All these last-mentioned Antelopes are pale in colour, being almost white, with the throat protected by long black hair. Whilst speaking of the Beisa Antelope, Mr. Blanford remarks that “the appearance of a herd of Oryx is very imposing. They are some of the most elegant and symmetrical of animals, the motions being those of a Wild Horse rather than of an Antelope. Their favourite pace appears to be either a steady quick walk or a trot; they rarely break into a gallop unless greatly alarmed. When frightened they dash off, sometimes snorting and putting their heads down, as if charging, raising their long tails, and looking very formidable. They are wary animals, though far less so than some other Antelopes. It is said that they frequently attack when wounded, and their long, straight horns are most deadly weapons.”
