Dinder. The southeasterly bank of the Blue Nile is a semireserva- 

 tion, where government officials only are allowed to hunt, and there is 

 mvich 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'Siii 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 oft' 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 arable 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,.
