me to try to kill more than the four actually needed for 
the public (not private) Museum to which our collections 
were going. It is of solitary habits, and is found only 
in certain vast, lonely marshes of tropical Africa, where 
it is conspicuous by its extraordinary bill, dark colora¬ 
tion, and sluggishness of conduct, hunting sedately in 
the muddy shallows, or standing motionless for hours, 
surrounded by reed-beds or by long reaches of quaking 
and treacherous ooze. 
Next morning, while at breakfast on the breezy deck, 
we spied another herd of the saddle-marked lechwe, in 
the marsh alongside, and Kermit landed and killed one, 
after deep wading, up to his chin in some places, and 
much hard work in the rank grass. This buck was 
interesting when compared with the two I had shot. 
He was apparently a little older than either, but not 
aged; on the contrary, in his prime, and fat. He had 
the white saddle-like mark on the withers and the white 
back of the neck well developed. Yet he was smaller 
than either of mine, and the horns much smaller; 
indeed, they were seven inches shorter than my longest 
ones. It looks as if, in some animals at least, the full 
size of body and horns are reached before the white 
saddle-markings are acquired. The horns of these 
saddle-mark lechwes are, relatively to the body, far 
longer and finer than in other species of the genus ; 
just as is the case with the big East African gazelle 
when compared with other gazelles. 
That afternoon, near the mouth of the Rohr, which 
runs into the Bahr el Ghazal, I landed and shot a good 
buck of the Vaughan’s kob, which is perhaps merely a 
sub-species of the white-eared kob. It is a handsome 
animal, handsomer than its close kinsman, the common 
or Uganda kob, although much less so than its associate
