Dinder. The southeasterly bank of the Blue Nile is a semireserva- 
tion, where government officials only are allowed to hunt, and there is 
much less travel and native settlement. The same writer mentions 
that Elephants occasionally come to drink on this south bank at Zu- 
murka, nearly opposite from Karkoj, and opposite Abu Tiga and Om 
Bared, farther up. The only place where we learned of their presence 
was opposite Magangani, a few miles below Roseires. Here we heard 
them trumpeting and blowing water about one evening in January, 
but were unable to see the animals. They still frequent the Dinder 
River. In 1901, I. C. Johnson found them at Durraba and shot one 
near there. On our journey up this river we first found their tracks 
and droppings in the dry river bed above that place at a camp site, 
Mesharat el Kuka. The spoor was old, however. From this point on 
up the river to Um Orug, our farthest camp, there was abundance of 
old sign, and many broken trees twisted off by the huge beasts. A 
poaching party of Abyssinians had killed an Elephant here two or 
three months before and the herd had evidently left the region; 
possibly they had crossed over to the Rahad, or as some of the native 
hunters supposed, they may have retired to a khor or dry water course 
to the south. The red-barked Acacia, whence the gum arabic is 
obtained, is the favorite food tree of the Elephants in this region. We 
constantly came upon large trees of this species, often eight inches in 
diameter at two or three feet from the ground and twenty-five or 
thirty feet high, that had been broken down and the topmost twigs 
eaten. They are broken in a rather characteristic manner, at about. 
two or three feet from the ground, and the trunk partly twisted off. 
Others are broken over and uprooted, and the topmost twigs chewed.

The type of this species was obtained by Mr. A. L. Butler at Gebel 
Fazogli, one of the foothills of the Abyssinian highlands on the south 
side of the Blue Nile. Mr. Wroughton, in describing it, records a 
second specimen from Gebel Ain on the White Nile. During our stay 
at Fazogli we obtained three specimens and saw a few others. They 
live in dens among huge boulders and though somewhat shy, have a 
curious way of appearing suddenly at the openings of their retreats,
