typically normal, not extending beyond posterior notcli of 

 nostrils ; no face-glands, but a bare, and probably glandular, 

 patch of skin below each ear ; tail bushy ; foot-glands repre- 

 sented, at most, by the duct of the glands existing in Pdca ; 

 one or two pairs of inguinal glands ; coat hairy ; skull light, 

 with large lachrymal vacuities, small auditory buUfe, and the 

 premaxillffi not reaching the nasals. 



The distribution is practically co-extensive with that of 

 the subfamily. 



The two subgenera may be distinguished as follows : — 



A. Muffle extending beyond notcli of nostrils ; one pair 



of inguinal glands Eleotragus. 



B. Muffle normal ; two pairs of inguinal glands Bedunca. 



The following is a " key " to the species : — 



A. Colour tending to grey, distinctly grizzled ; head 



and neck more fulvous, tail very bushy. 



a. Size small, colour rich, with a rufous tinge, 

 skull broad, horns slightly hooked at 

 tips, muffle normal B. fulvomfula. 



h. Size large, colour paler, with a fulvous tinge, 

 skull narrow, horns more hooked at tips, 

 muffle extending beyond notch of nos- 

 trils jB. arundinum. 



B. Colour yellower and less grizzled, head and neck 



like body, tail less bushy. 

 Size medium or small, horns, as a rule, 



abruptly hooked at tips B. redunca 



1. Subgenus ELEOTRAGUS. 



Eleotragus, (rray, List Mamm. Brit, Mus. p. 165, 1843. 



Muffle inflated and extending beyond line of posterior 

 notches of nostrils; a single pair of large inguinal glands 

 -opening forwards along sides of abdomen, away from teats.*
