NKOTRAGINiE l-Lfi 



A large species, with long wavy hair and complete absence 

 of a dark frontal patch. General colour bright orange-fawn, 

 deeper along dorsal line, with the tips of the hairs cream and 

 their bases whitish ; forehead uniformly orange-fawn. Skull 

 relatively large and massive, with great development of the 

 bridge across the rostrum in front of orbits, and the con- 

 sequent marked concavity of the facial profile ; nasals 

 depressed ; lachrymal depression large and deep ; horns short; 

 and stout, inchning strongly backwards, as in montana, and 

 ridged only at base. Basal length of skull 6 inches (152 mm.), 

 greatest width 3/^ (84 mm.), length of nasals 2-iJ- (67 mm.), 

 of upper row of cheek-teeth 2j^ (52 mm.). 



The skull approximates to that of 0. cottoni, in which the 

 basal length is 5| inches (145 mm.), but differs by the more 

 backward inclination of the horns, resembling in this respect 

 0. montana, in which the basal skull-length is 6^ inches 

 (156 mm.). The hair is brighter and richer in tone than 

 that of cottoni, and quite different from the grizzled fawn of 

 montana ; while in its waviness it differs from both.
