horns. It is perhaps a dwarf form of the dorsalis-grouip, with the 

 black replaced by grey, and the chestnut much lightened in tone. 

 Were there not, however, so many specimens known, all alike, one 

 might be forgiven for supposing it to be a hybrid between 0. coro- 

 natus and C. maxwelli, the former being responsible for the rufous, 

 and the latter for the grey in its generally piebald appearance.

Size small. General colour pale rufous, broadly banded with 

 black. Face, ears, neck, and shoulders rufous or chestnut, except 

 the nasal region, which is blackish. Back from withers to rump 

 pale rufous, conspicuously banded transversely with deep shining 

 black. Under surface from chin to anus pale rufous, slightly paler 

 than the ground-colour between the bands. Limbs rufous, but 

 with broad black patches on the outer surfaces of the forearms and 

 lower legs, and with the phalanges black all round. Heels with 

 large glandular tufts of black hair on their postero-inferior surfaces. 

 Tail rufous, more or less mixed with black above, white below. 



Horns in the same line as the nasal profile : — 



(5 . Short (barely two inches long), conical, tapering, sharply 

 pointed, their greatest basal diameter going about 2j times in their 

 length. 



$ . Short (less than one inch in an adult), smoother than in the 

 male, but otherwise similar in character. 



Skull stoutly built. Nasal region broad, flat, parallel-sided. 

 Anteorbital fossae very shallow and little prominent, their bottoms 

 28 to 31 mm. distant from one another. Frontal region not spe- 

 cially swollen. Horn- cores so pressed downwards and backwards as 

 to cause marked depressions behind and below them on the parietals. 

 Palate with its three posterior notches about level. 



Dimensions. — S- Height at withers 405; ear 75 ; hind foot 175 

 (in a female, rather older, 185). 



Skull — basal length 148; greatest breadth 72; orbit to gnathion 

 87 ; nasals, length 63, greatest breadth 36*7 : muzzle 55 ; length of 

 upper molar series 48. 



Hab. Liberia. 



Long only known from pieces of flat skin, this remarkable animal 

 has now been made thoroughly familiar to mammalogists through 

 the exertions of Dr. J. Biittikofer, who collected many specimens 

 of it, and of Dr. F. A. Jentink, who described them {II. cc.). 

 Although its plan of coloration, possession of heel-tufts, peculiar 

 parallel-sided skull, depressed horn-cores, and shallow anteorbital
