218 Col. R. Meiuertzliageii on the [Ibis, 



Locustella fluviatilis. 



The Kiver- Warbler was only obtained once, on 30. ix. at 

 Kafa. The specimen is curious in having no trace of the 

 greenish tinge, which is quite distinct in the series both at 

 Tring and in the British Museum. Wino- 71 mm. 



Acrocephalus arundinaceus. 

 ^1. a. zarudmji Hart. 



Scarce on autumn passage at Rafa. First seen on 20. viii. 

 and last on 10. ix., but always singly. Of three obtained, 

 the wings of males measure 95 nnn. and that of one female 

 91 mm. All birds are in full l)ody moult, though the wings 

 are complete. 



Not noted on spring passage. 



Acrocephalus scirpaceus. 



A.s. scirpaceus (Herm.). {=-streperus Vieill.) 



Noted on autumn passage at Rafa from 15. viii. to 7.ix., 

 after which it became scarce, the last being seen on 2G. ix. 



On spring passage it occurred at Ramleh and in the Wadi 

 Rubin from the second week in March to 27. iii. 



Not observed in summer. 



Of seven obtained, the wings of live males vary from 

 64 to 67 mm. 



Acrocephalus palustris (Beclist.). 



Occasional on passage at Rafa from 15. viii. to 3. ix. 

 As this species could only be identified when it condescended 

 to use its voice, and as it was comparatively silent on 

 passage, possibly many were overlooked, for we failed to 

 discriminate between Reed- Warblers, Marsh-Warblers, and 

 Hippolais pallida, unless we heard them call or actually 

 handled them. 



Acrocephalus schcenobaenus (L.). 



First observed on autumn passage at Rafa on 20. viii., 

 when a few were scattered over the desert scrub, looking 

 very lost and tired. I'liey remained till 26. viii., after 

 which none were seen till 6. ix., when one was caught alive
