Hippolais pallida. 



//. i>. elceica (Lindermayer) Isis, 1845 (Greece). 



This race is paler and greyer than //. p. pallida from 

 Egypt and southern Europe, and is very distinct when seen 

 in a large series. 



Very common on autumn }>assage at Rafa from 13. viii. to 

 22.x. The spring arrival in southern Palestine was not 

 noted, but the birds bred plentifully round Jaffa, nesting in 

 orange trees, or sometimes in colonies in reeds, seventeen 

 nests being found in the former and five in the latter. A few 

 laid early and had young Ijy 10. v., but most had eggs from 

 18. V. to 31. V. 



Of eight obtained, the wings of four males measured from 

 65 to (J9 mm. 



Sylvia hortensis. (= orpliea.) 

 S. h. crassirostris Oretzschm. 



A few were seen on autumn passage at liafa from 15. viii. 

 to 7. X., but they were never common. They were also 

 common on Mount Carmel in the latter half of April, but 

 were not found nesting, though they undoubtedly were 

 doing so. 



This form is readily distinguished from the western race 

 by the very much whiter under parts. 



Sylvia borin (Bodd.). {St/lvia hortensis auctorum.) 

 The Garden- Warbler was first observed on autumn passage 

 at liafa on 27. viii. and soon became common, birds of the 

 year predominating. It became scarce on 18. ix. and was 

 not seen after 28. ix., except for one on 6. x. 

 No records made of spring passage.

*S'. a. alrii-apilla (L.).
