388 On two new Central- African Antelopes. 



although its differential characters are of almost as impor- 

 tant a nature as in the case of the Hartebeest, there is no 

 interruption in the range, and therefore, as intermediate 

 specimens will certainly be found, I propose only to make a 

 subspecies of it. 

 It may be called 



Connoclioites iaurinus alhojubatuSj subsp. n. 



Distinguished from C. taurinus typicus by the long mane 

 which runs along the centre of the throat being white instead 

 of black, including the tufts on each side of the angles of the 

 lower jaw. Coloration in other respects the same. 



Skull somewhat shorter, especially in the muzzle, and 

 the anteorbital depressions more strongly marked. Ilorns 

 directed somewhat downwards on each side instead of hori- 

 zontally outwards, and their bases much more expanded and 

 with prominent bosses on their upper aspects. 



Measurements of the typical skull : — 



Basal length 430 millim., greatest breadth 198 ; occiput to 

 nasal tip 428 ; nasals, length 215. 



Horns*: greatest length round curve behind 494 (=I9i 

 in.) ; greatest circumference at base 842 ( = 13^) ; greatest 

 spread, measured to the outer side of the horns, <6b2 ( = 25f) ; 

 tip to tip 414 (=16|); tip to tip round outer curve and 

 across forehead 1186 ( = 46f). 



Hah. Uganda [F. J. Jackson). 



Although I have taken Mr. Jackson's fine example as the 

 type of this new subspecies, I believe it will be found that 

 many of the East- African specimens hitherto considered to 

 be the common form really belong to it. Certainly several 

 Kilima-njaro heads that I have seen have white throat-manes, 

 while the South-African specimens invariably have black 

 ones. In fact it seems probable that, just as the recently 

 described Oryj; oallotis^ with its long black ear-tufts, repre- 

 sents in East Africa the 0. gazella and 0. beisa, so C. tauri- 

 nus alhojuhatus represents throughout that region the typical 

 black-throated race. Where the two forms, if at all, pass 

 into one another remains to be seen ; but it is evident that 

 they are certainly different geographical races, and ought to 

 have different names accordingly. 



• All these measurements are very difficult to take with any exactness, 

 and prohably no two observers would make them precisely the same.
