External Characters of Ruminant Artiodactyla* 369 



Owen correctly recorded the presence of inguinal glands 

 in this species, but gave no particulars. They are, as a 

 matter of fact, peculiar. On each side of the mammae, 

 which are arranged in a quadrilateral, and rather far out 

 from them, is a large orifice opening backwards and inwards, 

 not outwards, and this leads into a pouch about 3 inches 

 deep which runs obliquely forwards and outwards along the 

 depression between the thigh and the abdomen. The area 

 round the mammae and the glands is naked, and the secre- 

 tion of the glands has a starchy smell, like flour-paste. 



For information as to the structure of the penis, see under 

 Re dune a (q. v. infra). 



On the strength of the information regarding the rhinarium 

 and inguinal glands I gave him in 1914, Mr. Lydekker 

 (Cat. Ung. Marara. ii. p. 203) granted subgeneric rank to 

 Eleotragus. But, as I pointed out to him at the time, the 

 characters which distinguish the type-species of Eleotragus 

 from that of Redunca (olim Cervicapra) are quite sufficient 

 for generic admission. The structure of the rhinarium 

 affiliates Eleotragus with Pelea, and distinguishes it from 

 Redunca. On the other- hand, the absence of pedal glands 

 and the presence of inguinal glands show affinity to Re- 

 dunca and departure from Pelea. In the direction of the 

 inguinal glands and in the presence of only a single pair, 

 representing the shallow anterior pair of Redunca, Eleotragus 

 is distinct from that genus. 



Genus Redunca (olim Cervicapra)*. 

 Redunca redunca, Pall. (p. 913). 



A male example of this species from the Sudan (G. Blaine), 

 and probably referable to the race described as cottoni, re- 

 sembles in every particular, so far as the characters under 

 discussion are concerned, the examples of the typical race of 

 the species from Senegambia which I described in 1910. 



The rhinarium (fig. 1, D, E, F), viewed from the front, has 

 a convex upper margin ; the nostrils are about as widely 

 separated as in Eleotragus, and, as in that genus, there is 

 scarcely a trace of naked skin below them ; the philtrum is 

 as wide above as the internarial septum, narrow inferior ly, 

 and expands slightly where it passes into the gum of the 

 upper lip ; it is mesially grooved up to the level of the lower 



* On the evidence supplied by Palmer, I follow Lydekker in adopting 

 Redunca for Cervicapra, the latter being a synonym of Antilope.
