ORDER RUMINANT1A. 193 



six inches long, perfectly smooth, bent as in the former, and 

 in volume something more considerable. These may be- 

 long to an unknown species, but it is presumed that they 

 are mere indications of age, with, perhaps, the aid of art ; 

 and as we have now before us a horn of the Caffrarian 

 species nearly in the same state, this conjecture acquires 

 the weight of certainty. 



With the Orygine group we class a subordinate racemus, 

 more anomalous in characters, but still osculating with it 

 by the position of the horns on the frontals, their length, 

 slender form, and terminal point, and their community to 

 both sexes — the insignificance or absence of the lachrymary 

 sinus — the ovine nose, large stature, and even by the marks 

 on the face, — yet assuming other characters which lead to 

 the succeeding groups. 



The Addax. (A. Addax.) The first impression on 

 seeing this animal is that of an oryx with spiral horns, 

 and upon examination this impression is not weakened, 

 although Caius in Gesner, de Capris Silvestribus, figures 

 the horns, and assigns them, with justice, to Strepsiceros. 

 Nomenclators have, in this instance, misplaced that name, 

 and given it to one which the ancients appear not to have 

 known : the words of Pliny prove that he did not mean 

 the creature of Southern Africa, at present distinguished 

 by that designation, and still less that he meant to indicate 

 the Cretan Sheep. His (Cornua) " erecta rugarumque 

 ambitu contorta et in Laeve fastigium exacuta, ut Lyras 

 diceres," is not perfectly applicable to either of the above, 

 but completely to the animal before us. Hence we have 

 no hesitation in adopting the name of Addax, which the 

 Roman naturalist gives as the local one of his Strepsiceros, 

 and in adopting on this head the opinions of Professor 

 Graetzmer. Shaw seems to have known only the horns of
