Show 428 MR. O. THOMAS ON THE ANTELOPES [May 17, about equal to the distance between the anterior canthus and the rhinarium. Colour grizzled yellowish grey, with rufous face, brown nasal mark, and brown feet, just as in the grizzled varieties of C. yrimmii, of which it is obviously the Abyssinian representative. Horns ( 3 ) set up at an angle above the line of the nasal profile, but not so markedly as in C. grimmii. 74 m m . long, evenly tapering, their basal diameter going nearly 5 times in their length. Skull, besides being actually smaller, shorter and broader in proportion than in C. grimmii. Distance between orbit and gnathion only just about equal to the zygomatic breadth. Anteorbital fossae of medium depth, defined above by a well-marked ridge, their bottoms about 14 mm. apart. Mesial notch of palate about 9 mm. in advance of the lateral ones. Dimensions.- 3 • Height at withers 455 ; ear 90 ; hind foot 220. Skull-basal length 131; greatest breadth 73#5; anterior rim of orbit to gnathion 74; nasals, length 51, breadth 30; muzzle 45; upper molar series 46'5. Hab. Abyssinia (Brit. Mus.). This species is no doubt the Antilope madoqua of Riippell -, but not the earlier described A. madoka of Hamilton Smith2, which is Salt's Antelope (Nanotragus saltianus, Blainv.). Both names are founded on the native name Madoqua or Madoka assigned by different authors to one or other of the two species, and probably used indiscriminately for either. Hamilton Smith's namebeiug happily antedated by De Blainville's "•A. saltiana," and Ruppell's incapable of adoption, as having been used before, we are fortunately able to rescue both these beautiful little species from the clutches of this barbarous and doubtful native name. 18.
