The Western or tj^pical Chiffchaff was abundant during 

 my visit in March. Amongst the numbers seen I believe 

 that I also saw the Eastern P. c. abietina, but as no specimens 

 were obtained I cannot say for certain. 



I might here mention that amongst the vast numbers of 

 ChifFchaffs which frequent Egypt during the winter months 

 there are many which have a most peculiar call-note — a 

 shrill chirp — totally unlike the call-note of the typical form. 

 I now have a number of specimens of these birds, which 

 differ from the typical P. collybita in being less greenish 

 above and usually much whiter below, and although they are 

 of small size I believe them to be referable to the Eastern 

 P. c. abietina. 



In his most valuable work — to which frequent reference 

 is made in this paper, and to which I am greatly indebted — 

 Dr. Hartert gives the measurements of the Eastern form as 

 larger than those of the typical Chiffchaff. It must be 

 borne in mind, however, that Chiffchaffs differ very con- 

 siderably in si^e individually.

I obtained no specimens of Bonelli^s Warbler in the 

 Wadi Natron although one or two examples were seen, 

 therefore I cannot say which subspecies occurs there. P. b. 

 orientalis (Brehm) is the common form occurring in Egypt, 

 though I have one specimen of the typical form obtained by 

 Mr. J. L. Bonhote in the Giza Province. I hope to get 

 specimens of this Warbler from the Wadi Natron later.]

On April 28th, 1910, Mr. Balboni shot a female Wood- 

 Wren, which he kindly forwarded to me. This example is 

 one of the very few specimens I know of this, the typical, 

 form from Egypt. P. s. erlangeri Hart., is the commoner
