convex anteriorly, and in some cases more or less distinctly 

 lyrate, always with well developed ridges ; tail moderately 

 or very short ; nose normal and mnzzle hairy ; face-glands 

 usually present; inguinal glands present or absent; teats 

 usual 2, rarely 4; glandular knee-tufts generally present; 

 lateral hoofs retained ; feet with a large interdigital cleft, as 

 in Bubalinw (vol. ii, p. 2), and foot-glands in each pair, 

 which form the deep cleft Math a long aperture on the front 

 of the pasterns, and the web extending forwards as a close 

 fold of integument from the " heel " towards the front of the 

 hoofs, so as to separate the cavity of the gland from the space 

 between the hoofs ; tail short or medium. Skull with 

 supraorbital pits, and usually lachrymal depressions and 

 lachrymal vacuities ; upper molars, as in the three preceding 

 subfamilies, of the tall, naixow, caprine type ; three pairs of 

 lower premolars, except in Antidorcas. Face-markings, 

 which appear late in life, generally in the form of alternating 

 light and dark streaks ; these in some cases disappearing 

 and leaving the whole face white. 



The range of the subfamily includes south-eastern Europe, 

 western and central Asia, the Indian Peninsula, and Africa.
