194 MAMMALIA, 



Plunging Antelope.) A light fawn coloured brown ; some white 

 beneath the under jaw; a black line on the external face of the 

 limbs. It derives its name from the manner in which it plunges 

 into the bushes when pursued. 



A. oreotragus, Forst.; Klip-Springer of the Hollanders; Buff. 

 Supp. VI, pi. xxii; Schr. 259. (The Rock-Springer.) Distin- 

 guished by its stiff brittle hair, which is of a greenish yellow. (1) 

 The smallest Antelopes are comprehended in this division. 



Jl. grimmia, h.; F. Cuv. Mainmif. (The Grimme.) Fawn 

 coloured grey; the forehead blackish ; a small tuft of hair on 

 the top of the head. 



A. pygrme a, F&IL^F. Cuv. MsimmiL (2) (The Guevei.) Ash 

 coloured; a pale blackish line along each side of the forehead. 



e. Jlnnulated horns with a simple curve, the points directed forwards. 



The REDUNCiE of Smith. 



A.redunca, Buff. XII, pi. xlvi ; Schreb. 265. (The Nagor.) 

 Reddish brown. From Senegal.(3) 



/. Horns annulated, straight or but slightly curved, and longer than the 

 head. The Oryx of Smith, in part. 



Ji. oryx. Pall.; erroneously termed Pasan by Buff. Supp. VI, 

 pi. xvii ; Cope 6'Aamois of the Hollanders. (4) (The Oryx.) As 

 large as a Stag, with slender horns two or three feet long, 

 straight, pointed, round, the lower third obliquely annulated and 

 smaller in the female ; hair ash coloured ; head white, barred 

 with black ; a black band on the spine and one on each flank; a 

 deep chesnut spot on the shoulder, and one on the thighs ; tail 

 long and blackish, and the hairs of the spine directed towards the 

 neck. It is found to the north of the Cape, and in the interior 

 of Africa. The length of its hoofs, which is greater than in the 

 other species, enables it to climb rocks, and it prefers moun- 

 tainous districts. (5) 



(1) Add A. quadriscopa. Ham. Smith. 



(2) The figure of Schreb. 260, 1$, is too red; in that of Shaw, Gen. Zool. Vol. II, 

 Part II, pi. clxxxviii, the horns are too large. 



(3) Add the Ritbock {Jl. eleotragus). The Ourebi {.i. scoparia). It is very neces- 

 sary to observe that many Antelopes, while young, have horns of this form bent 

 forwards. 



(4) M. Lichtenstein has remarked, that as this Antelope with long straight horns 

 is only found in the south of Africa, it is not probable it is the Oryx. It is rather 

 the following species. 



(5) The A. leucoryx, Schr. CCLVI, B, or the White Antelope of Penn. taken
