208 CLASS MAMMALIA. 



same, the name of the latter must of course be struck out 

 of the list, and Dama alone retained ; and it follows also 

 that then the species will extend from the Nile to Senegal. 

 The Springer Antelope. (A. Euckon.) This beautiful 

 animal is the largest of a small subordinate group, 

 several of which seem to have been noticed by the an- 

 cients indiscriminately under the name of Dorcas, origi- 

 nally applied to the Roebuck. The Springer resembles 

 the Dorcas of nomenclators, but is nearly a third larger 

 in size. The head is rather short, with somewhat of the 

 expression of a Iamb ; the neck is slender, the body com- 

 paratively bulky, and the legs slender and elegantly turned. 

 In common with the rest of the Dorcades the croup is more 

 elevated than the shoulders ; this conformation appearing 

 to increase in the inverse ratio of their stature, for Py- 

 gargus has the line of the back horizontal, and Corinna 

 and Cora the croup most raised; Mytilopes shews it in a 

 small degree, and the Springer more. Independent of the 

 difference of relative size, we may take the greater deve- 

 lopment of the hind quarters as an index of the compara- 

 tive powers of bounding and velocity of motion : but the 

 character most remarkable and unique in the Springer, 

 consists in two folds of the skin ascending from the root of 

 the tail, and terminating upon the croup ; they dilate when 

 the animal is bounding, and expose a large triangular 

 space, otherwise concealed, of pure white-coloured hair, 

 edged by two dark streaks, which form the covering 

 borders. The general colour of the hair is a pale fulvous 

 dun ; the face, mouth, inside of the ears, breast, belly, pos- 

 terior part of the legs, tail, and croup, within the above- 

 mentioned space, white ; the end of the tail is furnished 

 with a few black hairs ; a broad dark-brown band divides 

 the white from the fulvous along the flanks, from the elbow 

 to the hip, and another separates the white colour of the 

 buttocks, ascends on the edges of the folds on the croup,
