84 Mr. J. H. Gurney, Jun., on the Ornithology of Algeria. 



57. Sylvia orphea, Temm. Orphean Warbler. 

 Tibrem. 



58. Sylvia ATRiCAPiLLA (Linn.). Blackcap. 



Very abundant about Algiers in February, and perhaps in 

 summer also ; but it is difficult to see small birds when the trees 

 are in leaf. It is equally common at Miliana, where I counted 

 thirteen birds on one tree. 



59. Sylvia hortensis (Gmel.). Garden Warbler. 

 Only one shot. 



60. Sylvia MELANOCEPHALA (Gmel.). Black-headed or Sar- 

 dinian Warbler. 



Manifests great alarm when it has not even finished building 

 its nest. The female, with trailing wings, utters incessantly a 

 low but angry note within two feet of the intruder ; while the 

 male (hardly opening his wings) leaps from twig to twig, making 

 the small boughs shake, and in the extremity of his resentment 

 essays to erect a few small feathers in imitation of a crest. They 

 fly with their tails spread, but close them on alighting. Some 

 females are darker than others, especially about the head. I 

 shot a male with a few white feathers appearing in the crown, 



61. Sylvia suBALPiNA (Bp.). Subalpine Warbler. 

 Two in the Mzab and one at Tibrem. 



62. Sylvia cinerea, Lath. Whitethroat. 

 Laghouat. 



63. Sylvia conspicillata, Marm. Spectacled Warbler. 

 Tibrem. 



64. Melizophilus undatus (Bodd.). Dartford Warbler. 

 Oran and Algiers. 



65. Phyllopneuste trochilus (Linn.). Willow Wren. 

 Abundant nearly everywhere. Towards the end of March 



the multitudes which winter in the Tell migrate northwards and 

 give place to others. Though I frequently thought I heard the 

 ChifFchafF, the birds on being shot nearly always proved to be 

 Willow Wrens. I am convinced that the true Chiffchaft" is far
