This species is of precisely the same colour as the preceding, and 

 differs from it only in being a slightly smaller bird with a somewhat 

 longer bastard primary. Possibl}- the legs and feet may be a shade 

 paler in colour. No difference is observable in the shape or colour 

 of the bill, or in the rictal bristles. The wing formula is the same, 

 but the bastard primary is always longer than the primary- coverts, 

 extending beyond them from 0-1 to 0-8 inch, l.ength of wing 2-75 

 to 2-5 inches, tail '2-'2\3 to 2*0, culmcn 0-7 to 0-6, tarsus 0-9 to 0-8 ; 

 outside tail-feathers 0-15 inch shorter than the longest. 



There are no ajjparent differences of age, sex, or season beyond 

 those of the usual fading of colour and abrasion of the edges of the 

 feathers, which takes place diu-ing summer and winter. 



The Olivaceous Tree-Warbler is a regular summer visitor to 

 Palestine, Greece, Asia Minor, and probably Italy. Its breeding- 

 range extends eastwards through Persia to Turkestan, and south- 

 wards through Egypt to Abyssinia. Its winter quarters appear to 

 be unknown.
