Um Orug we saw in all a fair number, usually in pairs, with other 
antelope on the great ‘meres.’ One herd of fifteen was deemed 
unusual. I came upon a fine lone bull drinking at a pool of the river 
an hour before noon. It seemed much astonished, but was not 
thoroughly alarmed until it got my scent, when with a loud explosive 
“oof” it bounded away. 
GIRAFFA CAMELOPARDALIS (Linné). 
Nubian Giraffe. 
Cervus camelopardalis Linné, Syst. nat., ed. 10, 1758, 1, p. 66. 
Thanks to governmental protection, Giraffe are still present in small 
numbers in parts of the Blue Nile Valley and on the upper Dinder. 
Mr. A. L. Butler of the Game Preservation Department said that they 
had very noticeably increased of late years. We saw none during 
our sojourn along the Blue Nile, but discovered old tracks in numbers 
some miles back from that stream; these were made during the rains 
when the ground was soft and were still (in January) deeply impressed 
in the sun-baked soil. The first locality where these tracks were seen 
was among the gum arabic trees about Gebel Okalma, near El Mesha- 
rat. A few other tracks were found, some fairly recent, in crossing from 
the Blue Nile to the Dinder between Abu Tiga and Wad Shara Shara. 
On the upper Dinder we saw several small herds of Giraffe, usually on 
or near the open ‘meres’ or boggy areas overgrown with rank grass. 
A fine herd of ten was seen near Abiad, and later three others. Shortly 
below Um Orug we saw a herd of twenty-one and later another of 
twenty-five and after dark came upon a small herd that took headlong 
flight through the tall grass. Their chief enemy is the lion, and we 
several times came upon dead Giraffes that had evidently been killed 
by them. These were usually youngish animals with the epiphyses 
of the bones still separate. The lions do not eat the tough hide of the 
Giraffes but leave this carefully separated from the carcase, and even 
the vultures merely pick it clean. On a ‘mere’ near Abiad we found a 
Giraffe that seemed to have died from natural causes — an old and 
scabby-looking animal with no external wound apparently. The 
gathering vultures had only just commenced upon it. 
A few young Giraffes are caught alive yearly in this region by the 
natives, with government permission, to be sent to Cairo or elsewhere 
for zoological gardens. The natural gait of the Giraffe when walking,
