witli ranch arclied frontals and swollen nasals. Tooth-row 

 about half an incli longer than in tiie ally. Bony projections 

 on base of skull between anterior end of bullge much larger 

 and more prolonged — in B. eurycerus they do not extend 

 backwards between the bullae at all. Bullae larger, rounder, 

 and more inflated, those of the female still more developed 

 than those of the male. 



Horns of male very thick and massive, apparently decidedly 

 thicker at all ages than in true eurycerus ; the angles rounded 

 and but little marked ,• the surface rough and coarse, not 

 worn smooth, as is commonly the case in the allied form ; 

 dark blackish brown, the tips white. Horns of female pro- 

 portionally rather longer than in the male, slender, rounded, 

 m(5re closely twisted than in the male, and with about half a 

 turn more ; their general direction more nearly parallel to 

 each other, about as in the Lesser Kudu. 



Markings quite as in the typical form, but the general 

 colour seems to be a stronger and richer fulvous. Muzzle 

 prominently black. Dorsal line, from the withers backwards, 

 marked with black, except where the continuations of the lateral 

 vertical lines cut it with white. White flank-lines about ten 

 to thirteen in number. 



Measurements of the typical skull (J) : — 



Basal length 394 millim. ; greatest breadth 167; top of 

 nasals from palate 137 ; nasals 148 x 52 ; muzzle to orbit 235 ; 

 muzzle to front of anterior premolar 123 ; palate length 223 j 

 combined length of three premolars 51, of tooth-row 126. 



Horns: length round carves 870 millim. ( = 34;^ inches) ; 

 in straight line 725 millim. ( = 28^ inches) ; circumference at 

 base 286 millim. ( = 11^ inciies) ; greatest spread (outside) 

 455 millim. ( = 18 inches). 



A female skull has a basal length of 350 millim., and its 

 horns measure 686 millim. ( = 27 inches) round the curves, 

 615 millim. ( = 24j inches) in a straight line, with a basal 

 circumference of 177 millim. ( = 7 inches) and a greatest 

 spread of only 227 millim. ( = 9 inches).
