 The Dart ford Warbler was a very common breeding-bird 

 at H. R'Hira. The female shot had an egg in the oviduct.

Firecrests were common and breeding at the beginning of

Judging by its organs, the Willow-Warbler was breeding 

 at H. R'Hira.

The ChifFchaff was common, and a nest with two eggs

 to this species.

I can find no constant difference in skins of Wood- 

 Warhlcrs from Algeria and elsewhere. The figure given 

 by the late von Erlanger (J. f. O. 1899, Taf. v.) of the 

 European Wood- Warbler is, I think, from a faded 

 example, and many specimens from various parts of Europe 

 will be found to agree perfectly with his figure of the 

 Algerian bird. It is remarkable that there should be no 

 difference in the Algerian breeding-bird, because its song is 

 markedly different from that of the Wood-Warbler which 

 breeds in England. It is unsatisfactory to attempt to describe 

 the song, but the last notes to which we are accustomed in
