III. Genus ANTIDORCAS. 



Antidorcas, Sundevall, K. Svcnska Vet.-AJc. Handl. 1845, p. 271, 

 1847 ; Thomas and Sclater, Book of Antelopes, vol. iii, p. 53, 

 1897 ; 0. Neumann, Sitzber. Ges. nat. Freunde, 1906, p. 237 ; 

 Pocock, Proc. Zool. Soc. 1910, pp. 893 and 897. 



Distinguished from Gazella by the presence of a large 

 evertible dorsal gland, lined with long white erectile hairs, 

 extending from middle of back to rump, the absence of 

 inguinal glands, and the presence of only two pairs of lower 

 premolars; the number of upper prernolars being either 

 three or two. Neumann considers the genus, which is repre- 

 sented by a single South African species, nearly allied to 

 the large gazelles of the subgenus Nanger, and the horns 

 present in both sexes show a striking similarity to those 

 of Gazella soemmerringi, although shorter.
