on Birds from Shendi, Sudan. 17 
February 24tli^ March 2nrl, and Marcli 6th; the nest 
resembles that of Spiloptila damans, but is slightly smaller ; 
all those which we found were built in shrubs [Genista) 
about three feet from the ground. For some unexplained 
reason the birds always deserted them before any eggs were 
laid. 
39. Cercotrichas podobe (P. L. S. Miill.). 
19 (j^, 2i2 c?, 331 c?, 252 ? , 326 ? , 421 ? . 
The wing of the female is about 5 mm. shorter than that 
of the male. 
This species was somewhat uncommon at Shendi^ though, 
on account of its retiring habits, it was no doubt often over- 
looked. It bears a remarkable resemblance to our Blackbird 
both in its varied and flute-like song and in its manner 
of hopping about on the ground. It has a pretty habit of 
waving, and at the same time spreading out, its tail when 
perched upon a tree. 
40. Hypolais pallida (Hempr. & Ehrenb.). 
94 ? , 4-iO ? . 
This species was exceedingly common, especially frequenting 
the open scrub to\\Drds the desert. It was very often to be 
seen in pairs, and had all the appearance of being resident, 
but no nests were found. 
41. Sylvia orphea Temm. 
351 6 , 330 ? . 
The Orphean Warbler was frequently to be met with in 
the scrub along the river-bank. 
42. Sylvia rueppelli Temm. 
277 (^, 344 ?. 
Our two specimens of Riippell's Warbler were all that we 
saw. They were very shy and were met with in the most 
impenetrable portions of the scrub. 
43. Sylvia momus (Hempr. & Ehrenb.) . 
70 (5 , 187 J , 309 d . 
These specimens have been compared with the type of 
S. momus in the Berlin ^Museum, It is possible that even-^
