23. Lanius nubicus Licht. smc. Shot near Debasseh a few 

 miles north of Dueim on the 9 th of February and also near Goz 

 Abu-G-omr at the end of March. 



24. Laniarus erythrogaster (Ceetschm.). This exceedingly 

 beautiful shrike we observed several times from Abba Island 

 southwards. It frequented thick underwood and bushes. 



25. Nilaus afer Lath. smc. Shot at our farthest station at 

 Grhrab el Aish south of Kaka. 



26. Pomatorhynchus remigialis Hartl & Finsch smc. Shot at 

 our farthest station south of Kaka. 



27. Cercotrichas podobe (P. L. C. Muller) » m c. Shot along 

 the railway north of Shendy. 



28. Argya acaciae (Licht.). This babbling thrush was shot 

 in January near Wadi Haifa and at the end of May not far 

 from Gremiab (between Omdurman and the 6 th cataract). 



29. Crateropus leucocephalus (Cretschm.) smc. This bird 

 occurred in the bush along the river north of Dueim. 



30. Pycnonotus arsinoe (Hempr. & Ehrbg). We shot this 

 bulbul on the west bank of the Nile near Wadi Haifa, and ob- 

 served it along the lower section of the White River. 



31. Sylviella micrura (Rtipp.) smc. This species was shot at 

 our farthest station at Ghrab el Aish south of Kaka. 



32. Scotornis climacurus (Vieill.). Very common in the mi- 

 mosa scrub and in the thick grass jungles along the river. We 

 did not observe it until south of Dueim, but no doubt it occurs 

 also north of that place as well as at Shendy where it is found 

 to be common. 



33. Coracias abyssinicus Bodd. This beautiful roller we 

 came across for the first time even north of Dueim; I have 

 noted it from Debasseh, and it was probably observed already 

 nearer Omdurman. It ranges south as far as we went but did 

 naturally not occur along the swampbordered part of the river 

 between Gebelein and Kaka.
