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 
Connochetes taurinus albojubatus, 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. Horns 
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 (=19} 
in.) 3 greatest circumference at base 842 (=18%) ; greatest 
spread, measured to the outer side of the horns, 652 (=253) ; 
tip to tip 414 (=168); tip to tip round outer curve and 
across forehead 1186 (=46#). 
Hab. Uganda (£7. 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-Atrican 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 Orya callot’s, with its long black ear-tufts, repre- 
sents in East Africa the O. gazella and O. beisa, so C. taurt- 
nus albojubatus 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 probably no two observers would make them precisely the same.
