36 THE SPECIES OF THE ANTELOPE- 



to tlie order Ruminantia (p. 248), said under the heading 

 A. rupestris »that Prof. Lichtenstein appears not to have 

 » known the adult of either of the Steenbocks and parti- 

 »cularly the present, which is larger and more robust in 

 » structure than his Tragulus'", he however adds a new 

 important characteristic, namely that the hoofs ai^e rather 

 high^ shorty and black. 



In the collection of the Leyden Museum is a specimen 

 agreeing with Lichtenstein's (Forster's), Hamilton Smith's 

 and Smuts' Steenbok, that is therefore a specimen of the 

 true tragulus. Other specimens in our collection have the 

 ears much shorter than the head, the horns slightly curved 

 forwards and the hoofs more slender and less high. These 

 specimens agree with the description and figure given by 

 Selater and Thomas in the mentioned »Book of Antelopes", 

 part V, pp. 41 — 46, plate XXVII, fig. 1, s. n. Raphiceros 

 {Raphicerus in the text) campestris (Thunberg). Now as I 

 pointed out above it is quite impossible to make out what 

 species was meant by Thunberg with his campestris, so 

 that we are obliged to rebaptize this species. I propose the 

 name Horstockii. 



According to Dr. Selater and Mr. Thomas (1. c. p. 36, 

 note), Antilope rufescens H. Sm. belongs to the number of 

 pale-colored specimens » quite impossible and of little im- 

 portance to determine". There is however among our spe- 

 cimens a female individual so exactly agreeing with the 

 description of rufescens by Hamilton Smith (p. 249, plate) 

 as if he had our specimen before him at the moment he 

 wrote down this description : this is the so-called Vlakte 

 Steenbok and, as will later on appear, a very good and dis- 

 tinct species. 



Blainville's acuticornis has been called so after an incom- 

 plete skull in the collection of the Royal College of Sur- 

 geons, London ; the figure and description strongly remind 

 the horns of tragulus. It is however very likely that it is 

 merely a mutilated skull of Tetraceros quadricornis (see 

 Flower's Catalogue of the specimens illustrating the osteo-
