The following publication comprises a list of birds, which Count 
E. Königsegg and I collected in Sudan namely on the Blue-Nile and Binder 
in 1911—1912. The collecting came to pass in two instances, the first con¬ 
tinued from January to end of March 1911 and the second from December 
1911 until April 1912. I only accompanied Count Königsegg in his first 
journey, which led through Egypt to Khartoum and Senar, where the 
outfit was concluded. The march from Senar started on 26 th January with 
camels and donkies, and the following places were visited: El-Erediba, 
Blue-Nile (26. I.), Shalläl, Blue- Nile (28. I.) Senga, Biue-Nile (80. I.), 
Luieza, Binder (2. II.), Chamissa, Dinder (6. II.), Abu-Hashim, Dinder 
(7. II.), Beida, Dinder (11. II.), Khor-Em-Dul, between Dinder and Blue- 
Nile (16. II.), Karkodj, Blue-Nile (18. IL), Senga (24. II.), Senar (6: III.), 
in these places the collection was obtained. Count Königsegg extended 
his second journey southwards to or a little farther down to Roseires to 
complete collection already commenced. 
Our stay in Khartoum was determined for the shortest time, till the 
equipment was ready, yet I took occasion to visit the sandy desert in vici¬ 
nity of the town, on which sparsely low, thorny Mimosa bushes grow. Round 
this vegetation I met with Aurip asser luteus (Lichst.) in large flocks, then 
I observed Saxicola deserti. Temm., Saxicola isabellina Cretzm., Hirundo 
aethiopica , Blanf., Biparia littoralis (Lichst.), Tachornis parvus ( Lichst.) ; 
passing a little hill I saw three or four' Petronia brachydactyla, Bp. (probably 
a new variety s. pag. 598) of wich I killed one single specimen with my 
stick-gun. These birds came in sight later again, which are — it seems — 
not uncommon in those places, Butler, however, does not mention them 
in his various papers. 
Drawing near the Nile many kinds of winter-visitors were engaged 
along the shore, where there was not wanting the inevitable Geryle rudis 
(L.), havering over the water. Near the river large flocks of Calandrella 
brachydactyla (Leisl.) and Melanocorypha bimaculata, (Ménétr.) spread
