The animals of this subtribe are peculiar as being the only hol- 

 low-horned or Bovine Ruminants which are marked with white 

 stripes and spots. The bands are not very distinct in the 1m- 

 poofo or Eland, but they are easily to be observed in the female, 

 if it is looked at obliquely, which was brought home by Burke, 

 and presented to the British Museum by the Earl of Derby. 

 The skull, which somewhat resembles that of the Deer, has a 

 rather small nasal opening, no suborbital pit, and only a small 

 suborbital fissure. 



Colonel H. Smith forms of the larger species three of his four 

 subgenera of Damalis : he places the smaller kinds as a subgenus 

 (Tragelaphus) of Antelopes. 



Prof. Sundevall placed the genera here brought together in 

 two different families; the genus Portax with the Bovina, and 

 the others in the Sylvicaprina, or True Antelopes. 



M. Agassiz has observed, that the horns of the Strepsiceres and 

 the Sheep are twisted in the contrary direction. Mr. Ogilby has 

 justly observed, that the right horn of the Strepsiceres is twisted 

 in the same direction as the left horn of the Sheep, and vice versa.
