50. PhylloscopHS bonellii. (Vieill. Nouv. Diet, xxviii., p. 91.) 

 Bonelli's Warbler. 



Bonelll's Warbler returns in considerable numbers at the be^inninof of 

 April, and immediately disperses to its various haunts, especially frequent- 

 ing olive-yards and wooded hills, where it builds its domed nest on the 

 ground well concealed. 



Bonelli's Warbler visits Central and Southern Europe from the Atlantic 

 to Turkey in summer. It is not uncommon in Asia Minor, but has not 

 been traced east of Palestine. It winters in North Africa as far as 

 Senegal and Nubia. 



51. Hypolais oliveiorum. (Strickland in Gould's Birds of Europe, ii,, 

 pi. 107.) Olive-tree Warbler. 



This, the largest of its genus, is a late summer visitant to the north of 

 Palestine, where it breeds in small numbers in olive-groves. 



The Olive-tree Warbler is a denizen of Greece and Asia Minor. In 

 Algeria it is rare, though I have taken its nest and still possess the parent 

 bird. It has been taken also once in Egypt, in Abyssinia, and is stated 

 to be found in Fez. Nothing more is known of the distribution of this 

 most local bird. 



52. Hypolais Jipcheri. Tristram. P. Z. S., 1864, p. 438. Upcher's 

 Warbler. 



Though a specimen of this bird was taken in Palestine by Ehrenberg, 

 who named it Curnica languida, yet as his description is unrecognisable, 

 and has only been identified by the existence of the type at Berlin, the 

 name is excluded by the Stricklandian Code. 



Upcher's Warbler is confined, in Palestine, to the lower and cultivated 

 slopes of Lebanon and Hermon. It is exactly intermediate in size between 

 the Olive-tree and Pallid Tree Warblers. It is doubtful whether it 

 migrates further than up and down the mountains. It breeds in Palestine, 

 Egypt, Abyssinia, South-east Persia, Baluchistan, and Turkestan. In 

 this last country it is only a summer visitor. 



53. Hypolais pallida. (Hemp, and Ehr. Symb. Phys. Aves, fol. bb.) 

 Pallid Tree Warbler. 



This is the most common species of its family, especially in the lower 

 and warmer parts of the country. It reaches the Jordan valley in March,
