temple was white, with a white spot; the legs had a brown stripe 
down the outer side of the front; and the throat and rump brown, 
the latter without any white spot. 
Dr. Burchell, when speaking of the Bless bock, proposed to call it 
A. albifrons, as the name Pygarga has been used for both the 
Springer and the Bless bock ; but it is not certain if he intended by 
Bless bock this or the preceding species. Captain Harris’s figure 
shows the distinction of the species.

5. Damatis? Zesra. The Dorta. 
Bright golden brown, with numerous black cross bands narrowing 
at the sides; outer sides of fore and hind legs dark.

Skins without head and feet are alone known; they are brought 
down by the negroes. In the Catalogue of the Mammalia in the 
British Museum I have referred this species with doubt to Cephalo- 
phus. Mr. Ogilby (P. Z. S. 1836, 121) thinks it should be referred 
with the Harness Antelopes to Calliope. I am inclined, on account 
of the dark mark on the outside of the limb, to think it belongs to 
the genus Damalis. Mr. Whitfield believes it to be a species of 
Viverra. 
THE STREPSICERES. 
The animals of this family are peculiar as being the only hollow- 
horned or Bovine Ruminants which are marked with white stripes 
and spots. The bands are not very distinct in the Impoofo or Eland, 
but they are easily to be observed in the female, if it is looked at ob- 
liquely, which was brought home by Burke, and presented to the 
British Museum by the Earl of Derby. Their nostrils are near to- 
gether in front. They have four teats in a small udder. The horns 
generally incline backwards from their base; the skull, which some- 
what 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 sub- 
genera of Damalis: he places the smaller kinds as a subgenus (T’rag- 
elaphus) of Antelopes. 
Prof. Sundevall placed the genera I have here brought together in 
two different families; the genus Portax with the Bovina, and the 
others in the Sylvicaprina, or True Antelopes. 
The AFRICAN GENERA have large heavy horns, only the rudiments 
of a tear-bag, and their limbs are nearly equal; they have no sup- 
plementary lobes to the grinders, and the central cutting-teeth are 
enlarged above.
